Most, if not all, of the sampradayas of Vaishnavism, Saivism, Shaktism etc. have an initiation or diksha process for even common folks to be part of the particular sampradaya they are attracted to/meant for. Now, at least in the southern states to my knowledge, there are many smartha families that claim to be followers/devotees of one of the 2 major mutts associated with Adi Sankaracharya. My question is how do people/families in general claim lineage or association with a particular mutt if there was no initiation done? How to they accept either of the Sankaracharyas as their Guru? Because, to my knowledge, the sankara sampradaya does initiation process only for sanyaasis. Has Adi Sankaracharya given any instructions in this regard?
