Sri Chinna Jeeyar Swami awed the audience and devotees as He spoke the essence of all Vedic scriptures through His breath-taking discourse! The devotees poured in thousands. There is not a single rupee collected from anyone for such a valuable message, because Swamiji (and the lineage of gurus, including Ramanujacharya) strictly follow a tradition which believes that it is a fundamental right of everyone to know, and worship God as defined in Vedas!
But, with that fundamental right also comes a duty to serve God in every way possible (time, money, or support the functioning of temple through any other resources).
అనాహూతో అధ్వరం గచ్చేత్
In order to serve, pay respects, offer gratitude, and love such divine Deity form, scriptures state that every single one can happily attend the temple without any form of invitation.
