:-)), adi shankaracharya has made these groups of Sadhus, the Oldest one is Dashnami akhada, wiki says Shankar established 7 akharas, any ways shahi snan is only on snan happens at the end of mela butI guess there are 4 snans in one Kumbh mela, Kumb starts with Dhwaja Rohan of Akharas, as Dashnami is the oldest one so Kumbh's start is said to happen with Its dhwaja rohan and then later according to seniority , dhwaja rohan happens,
In Hinduism its a duty of a Grahasth to feed Ascetics But Its alwas reverse in Kumbh, when Sadhus return it to grahasths and Open Bhandaras or Langars for all
Kumbh Mela is the Oldest union of Human Being which happens every 12 years without distributing any invitations , it was same way even some 3000 years Before the Birth of Jesus Christ the way we see it now
