Those who support the theory of "Service to People is service to God" fail to understand the purpose for which a Temple stands. They should not forget that it is a great platform to unite people regardless of their caste or creed. All are equal in front of God and Temple worship is meant to create this feeling. All services to God are routed through different sections of devotees. In other words, the beneficiary in all services is undoubtably the Human being.
King Raja Raja Chola had nominated 400 dancers, 220 supporting artists and 50 Thevaram oduvars for the Big Temple at Thanjavur. Since the Temple had more than 1000 attendants, the King appointed barbers and laundry men and inscribed the names of those who served for the Temple. Temples were the breeding point for Arts and stood tall for providing life support to various sections of Public. That is why Service to God is considered as noblest in the world although some professions are compared to this only because some lives are saved while in distress. On the other hand, Service to Temples is not a short living phenomenon.
Look at the Noon-meal scheme at many Temples. Feeding the poor devotees is considered as the Holiest service in our Puranas. Even those who wish to feed the poor choose to do it through the Temples as the service can continue even in their absence. By taking the job directly, the exhaustive nature of the noble cause is restricted and becomes selective.
Rare species of Plants which are not normally grown elsewhere are planted inside the Temples and preserved . Some such plants are given the status of "Sthala Vruksham".
