The Platonic scale is based on the Great Year as explained by Swami Sri Yukteswar Giri.
The Great Year, is the term that some ancient civilizations use to describe the slow precession of the equinox through the twelve houses of the ancient zodiac, a period that takes about 24,000 years; 12,000 years ascending into a higher age, and 12,000 years descending into a lower age.These cycles bring about a complete change, both externally and internally.
The tuning frequency equation is based on this fact. The frequency is very low, so one has to raise the frequency to the range of hearing by multiplying with the necessary amount of octaves.
Precession now equates to one cycle in about 25,770 (25,920) years only because we are near apoapsis, the slow part of the elliptical orbit. According to Kepler’s laws, as the Sun moves towards periapsis, the rate will continue to accelerate and will average near 24,000 years.
The development of the mental virtue is gradually divided into four different stages in one period of 12000 years.
- Satya Yuga (Golden Age; 4800 years)
- Treta Yuga (Silver Age; 3600 years)
- Dwapara Yuga (Bronze Age; 2400 years)
- Kali Yuga (Stone Age; 1200 years)
Every age has an ascending and a descending period time in addition to the time of the Yuga itself. It is like a transitional period from one Yuga to the other and these are called “Sandhis”. Kali Yuga (1200 years) Sandhis is 100 years before and 100 years after its 1000 year long age. Dwapara Yuga (2400 years) Sandhis is 200 before and 200 after its 2000 year long age
Treta Yuga (3600 years) sanhis is 300 years before and after. Sataya Yuga (4800) Sandhis is 400 years before and after. Each of the Yugas has much influence over the period to time covered by it
Virgo is the sign opposite Pisces. The Autumnal Equinox is now falling in Virgo; the opposite point, the Vernal Equinox, is by force now falling in Pisces.Those who consider the Vernal Equinox to have chief significance, therefore say the world is now in the “Piscean Age”.
The Equinoxes have a retrograde movement in the constellations. When the Equinox will leave Pisces-Virgo, they will enter Aquarius-Leo.
The Great year is 24000 according to Swami Sri Yukteswar (1894). Present age of Dwapara Yuga (today 2010) is 310.The world will enter the Aquarius-Leo in A.D 2499.
