I seriously don’t remember where I plucked it from…
The capital of Vijaynagar appears to have been established on 18 April 1336, equivalent to Salivahana Saka 1127 Prabhava Chaitra Pournami, Sthiravaram Ratri (night) where all activities of Sankalpa were completed and the foundation stone was laid in Bahula Paksha Amavasya at Midnight.This is confirmed by Raya vachakam which is a contemporary document.
It is learnt that saint Vidyaranya Swamy made all the arrangements for the foundation laying ceremony. The saint by himself conducted mahasankalpam, invoked the deity of Vastu, determined the directions of North and South with the help of Dhruva Star and the Trisanku was erected. On East and Western directions Sankhas (conches) were arranged and molten gold of sixteen shades were poured in the foundation pit in large quantities. Sri Samrajya Lakshmi yantram was then placed and opposite to the site a reservoir was dug where his disciples were asked to wait and watch for his signal of most auspicious time for laying the foundation stone. The Saint conveyed to them that he would give an indication by ringing a bell and would blow a conch shell. A brick was tied to the end of a thin string, along with Vastu yantramu, Diamonds and Mercury and arrangement was made such that by slicing the thread, the brick would fall into the foundation pit at the auspicious moment. Making all these arrangements and instructing Harihara and Bukka Raya the Saint went over to the top of the hill and was engrossed in the astronomical calculations and was waiting for the auspicious moment. The Saint planned the time and state of various planets such that the capital and the Empire that was likely to be established would flourish for 3600 glorious years.
To the misfortune of Hindus, a Tantrik was worshipping lord Shiva at a place down the hill and after completing his worship rang the bronze bell and blew his conch shell loudly. Harihara Raya who was at the foundation pit awaiting the indication from the Saint immediately sliced the thread and the brick fell into the foundation pit before the auspicious moment arrived. Within a short time another sound of the bell and and blowing of conch shell was heard. Harihara and Bukka Raya ran to the top of the hill to enquire abount the two sounds at different moments. Vidyaranya Swamy lamented that the foundation stone was laid much before the auspicious time. He after examination of the time and planetary position at the instant of dropping of the foundation stone predicted that the empire would lost for 260 years and would be destroyed by the enemies due to inauspicious time of the ceremonial event. He also said that the prediction of sage Vyasa to him at Kashi has come true. It appears Sage Vyasa stated that the empire would last 300 years. The Vijaynagar city was thus established and the empire flourished for nearly three centuries from 1336 to 1646.
The glorious empire established with the blessings of Saint Vidyaranya Swamy in 1336 lasted for 310 years. However, it lost its glory after Tallikota Battle in 1565. The glory of the empire lasted for 229 years that is very close to the predictions of the saint. Although the saint took all precautions and planned for an empire to last 3600 years, the destiny did not smile at the foundation ceremony and the foundation stone fell at an inauspicious moment and destiny came out victorious.
