The Temple is a Place of God
Babaji's stand on these issues was very clear: the temple is a place of God, and should be open to every heart.
The utmost care is needed to maintain its sanctity.
The cleanliness of the murti and the decoration with colorful clothes were essential for maintaining the purity and the sanctity of the temple and attracting worshippers and devotees.
If the people whose duty it was to look after these arrangements did not bother about them, the result was that the temples ceased to be places for purification, and people actually came to be repelled by them.
Inner purity cannot come in an unclean and hostile environment.
