Only the uninitiated can deny the Sun

Western, or Tropical Astrology is entirely based on nature and the seasonal cycles that we experience in Europe (it is a Greek system.) When the Sun enters 0 degrees of Aries, we have the spring equinox which is when the Sun crosses the earth's equator. 

0 degrees of cancer is the summer solstice. 0 degrees of Libra is the Autumn equinox. Winter solstice is 0 degrees of Capricorn. As you can see, tropical, Western astrology perfectly reflects the seasons as it is a solar based system. 

Western astrology functions independently from the constellations and is not in alignment with the stars other than in name. 

Western astrology is not wrong, "frozen," or any other absurd term used by the people who have zero knowledge of western astrology which includes NASA and a lot of Vedic astrologers. How could the cycle of the Sun possibly be wrong? 

The tropical signs reflect the cycle of the seasons. Cardinal signs which are those that I listed above, fall at the start of a new season. Cardinal signs initiate changes and are natural leaders. Fixed signs (Taurus, Scorpio, Leo & Aquarius) represent the times of year when we are fully into a season and nothing is changing in nature. These signs are stubborn, loyal and resilient. The mutable signs (Gemini, Virgo, Sagittarius & Pisces) occur at the end of one season, right before the equinox or solstice. These signs are flexible and go with the flow. We take this formula and apply it to every planet in the birth chart, then we analyse the relationships between the planets. All of these planets represent different life areas. The angles in the chart change every 2 hours and also fall in different signs. 

You will not have the same birth chart as anyone else unless they were born on the same day, time and location as you. 

We are part of nature and reflect her qualities. The planets do not control anything, they are a reflection of life, the microcosm and the macrocosm. 

Scholars of tropical astrology recognise that the qualities of the signs are not interpreted in the same way as the constellations of the same names. For example, some stars in the constellation of Cancer are said the have the qualities of Saturn and Mars (planets of war, conflict, discipline and endings. Vastly different from tropical cancer which is ruled by the moon and said to be the archetype of the nurturing and fertile Mother. 

Claudius Ptolemy states in his work "Tetrabiblos" "The beginnings of the signs and likewise those of the terms, are to be taken from the equinoctial and tropical points. This rule is not only clearly stated by writers on the subject, but is also especially evident by the demonstration constantly afforded, that their natures and familiarities have no other origin than from the tropics and equinoxes, as has already been plainly shown. 

He mentions this issue several times in the Tetrabiblos. It's almost as if he anticipated the buffoonery and misconceptions surrounding Greek, Western astrology.

The equinoxes and solstices are a huge part of Vedic religion, as they are in all Indo-European or Aryan religions. Only the uninitiated will deny the power of the Sun. 

Western astrology, and the uncorrupted Vedic astrology both are based on the equinoxes and solstices. Modern Vedic astrologers cannot even agree on the starting point of the sidereal zodiac. How did this corruption happen? Quite simply when Astrology, which was an initiatory part of the mysteries, fell into the hands of the uninitiated.

Modern Native Tropical Proponents

In the late 19th century, S.B. Dikshita, in his book, History of Indian Astronomy, Part II, concluded that the Indian calendar should be based on tropical zodiac signs, not sidereal – because of the importance of the solstices and equinoxes in Vedic religion. Dikshita recognized the unlikeliness of conservative Indian culture adopting such a radical change and suggested that a partial reform would be to standardize a singular sidereal zodiac on the citrapakṣa ayanāṁśa.

Dikshita’s opinion was echoed exactly by the official Calendar Reform Committee, led by N.C. Lahiri and commissioned by the Indian Government in 1950. The first and second resolution in the committee’s official report was that the start of the year (and thus the zodiac) should be marked by northerly equinox. But they conceded that an ayanamsha can be applied “for religious purposes… as a concession to the prevailing customs.”

Again on page 7 of the report, when elaborating on standardization of the religious calendar, the committee wrote,

“This recommendation [citrapakṣa ayanaṁśa] is to be regarded only as a measure of compromise, so that we avoid a violent break with the established custom. But it does not make our present seasons in the various months as they were in the days of Varahamihira or Kalidasa. It is hoped that at not a distant date, further reforms for locating the lunar and solar festivals in the seasons in which they were originally observed will be adopted.”

It is clear that the seven extremely highly-esteemed scientists and scholars commissioned in this committee agreed that the tropical zodiac was correct, but a sidereal zodiac would be required to accommodate the prevailing customs. Thus, they viewed the sidereal zodiac as a compromise with tradition. I encourage all readers to read the committee's full report. Many esteemed native opinions in favor of tropical orientation can be found there.

In 1930 G.V. Krishnaswami published a paper entitled, Reform of the Indian Calendars, in which he says, “The method of placing the ayanas and the months on a sidereal basis in the Indian calendars is defective and hence there is a difference of about 23 days in the calculations.”

Among contemporary people at least three scholars – Krishen Kaul, M.K.A. Patrakam, and T.V. Sivaraman speak very openly against the sidereal zodiac. Several important religious leaders also. These include: Sri Swarupananda Saraswathi Maharaj of Dwaraka Mutt, Sri Jayendra Saraswathi Swamigal of Kanchi Mutt and Sri Gangadharendra Saraswathi Swamiji of Shri Sonda Swarnavalli Mutt.

Smug Sidereal astrologers - you are using a peasant form of astrology based on mistranslations by the ignorant. 

The following text could not be possible using a Sidereal Zodiac, only tropical:

Bhāgavata Purāṇa

Division 5, Chapter 21, Text 3:

sa eṣa udagayana-dakṣiṇāyana-vaiṣuvata-saṁjñābhir māndya-śaighrya-samānābhir gatibhir

The sun moves at varying speed between the northern solstice, southern solstice, and equinotical points.

ārohaṇāvarohaṇa-samāna-sthāneṣu yathā-savanam abhipadyamāno

Its rise towards the northern solstice, its fall towards the southern solstice, and its crossing the middle point can be known by measuring the days.

makarādiṣu rāśiṣv aho-rātrāṇi dīrgha-hrasva-samānāni vidhatte.

The days and nights grow longer and shorter, revealing which of the signs – Capricorn, etc. – the Sun is in.

Text 4:

yadā meṣa-tulayor vartate tadāho-rātrāṇi samānāni bhavanti

When the Sun is in Aries and Libra, the days and nights are equal.

yadā vṛṣabhādiṣu pañcasu ca rāśiṣu carati

tadāhāny eva vardhante

hrasati ca māsi māsy ekaikā ghaṭikā rātriṣu.

When the Sun is in the five signs starting from Taurus, the days grow longer and nights which grow shorter, month by month.

Text 5:

yadā vṛścikādiṣu pañcasu vartate

tadāho-rātrāṇi viparyayāṇi bhavanti.

When the Sun is in the five signs starting from Scorpio, the days and nights change in the opposite way.

The seven sages of India (Like the Greeks) used a tropical Zodiac with sidereal zodiac for nakshatras or fixed stars only. The reason why Vedic astrologers today only use the sidereal zodiac is because of corruptions and mistranslations during the Kali-yuga with the sacred information being used by people who were not initiated into the mysteries. The tropical Zodiac is a solar based system which is based on the ecliptic or apparent path of the Sun. It is exactly fixed to the seasons, the equinoxes and solstices. We live in the age of ignorance and lies - only in the kali-Yuga could so many people describe a solar based zodiac as false or out of alignment! 

Most Vedic astrologers have never studied western or tropical astrology and so they continue to use only the sidereal zodiac. And so they repeat the myth, over and over again, that the tropical zodiac is out of alignment with the stars when It was never a star based system, the signs in tropical derive their interpretations from the seasons. Instead of bleating continuously about the 24 degree difference due to the precession of the equinoxes, perhaps Vedic astrologers should educate themselves on Western astrology. I have studied astrology for 23 years, Western and (recently) real Vedic astrology. The most accurate way to practice astrology is to use sidereal nakshatras and tropical for the rest. The Sun enters Aries on the spring equinox and as a European I can literally see the evidence for Western astrology in the natural world around me. 

An American astrologer called Vic Dicara who has the ability to read Sanskrit has translated the texts correctly and I recommend checking him out on YT. Thankfully, some Indian astrologers who can read Sanskrit are open about the correct way to use astrology and have been speaking out about this issue. 

The Saptarishi Nadi is a collection of texts that discuss the horoscopes of the seven sages. The placements of the horoscopes simply would not be possible using a sidereal Zodiac, only tropical. I recommend reading this article, written by an Indian astrologer, to learn more:
