This is a Yantra of Shri Venkatesh of Tirupati Balaji; easily among the most worshiped deities in India. The Shrine is the most visited place of pilgrimage in India. It is the experience of devotees that their wishes get fulfilled by the grace of Shri Venkatesh and hence a lot of people from all walks of life visit the shrine.
The Yantra has to be prepared on a thick piece of copper and kept in the Pooja Place. The Yantra has to be kept on a piece of Yellow Silk Cloth and worshiped by offerings of scented flowers like rose, jasmine or mogra; the purple lotus and tulsi are also considered as favorites of Shri Venkatesh. It should also be offered an Agarbatti and a Diya of Pure Ghee.
If none of the above is possible; just a Darshan of the Yantra, everyday is sufficient. While worshiping the Yantra chanting this mantra is recommended.
