Temple was undergoing reservation. On left and right of pic is GARUDA the vehicle of Lord Vishnu. Devotees who are not getting married (boy or girl) eg my driver, came to this temple prayed with a Mala which they then took home and kept safely. After you find a life partner the couple come back to the temple with two malas made of flowers and offer to Varaha Perumal. My
driver actually did what I have described and then met his wife. Clicking pictures inside temple not permitted.
