A four-hour Shanti Homam Panchagavya Prokshana (ritualistic sanitisation) to undo the alleged desecrations that occurred during the YSRCP regime at Tirumala temple is underway now, temple sources said on Monday.

A Tirumala Tirupati Devasthanams (TTD) source confirmed to PTI that the ritual began at 6 am and will last till 10 am, aimed at propitiating Lord Venkateswara Swamy from the alleged sacrilegious practices such as mixing animal fats in making Tirupati laddus (consecrated sweet) and others.
