Shankracharya Swaroopanand Saraswati has sought a law on protecting cows and asked Prime Minister Narendra Modi to take initiatives in this regard.
He has also demanded a nationwide beef ban.
The seer, who was in Allahabad for a religious congregation, said late on Wednesday that with a pro-Hindu government at the centre, this was the right time to enact a law to protect cows.
He also slammed retired Supreme Court (SC) judge Justice Markandey Katju's statements which criticised beef ban in Maharashtra and Haryana.
He, however, slammed the Bharatiya Janata Party (BJP) and other Hindu organisations over 'Ghar Wapsi', and added that the process was wrong.
"Mere changing of the process of following a religion does not make much of a difference," he added.
