Why should a person attend the Kumbh Mela?

Visiting the Kumbh Mela to take a dip in the holy waters and cleaning the sins committed in a lifetime is a very superficial motive to attend the Kumbh Mela. The Kumbh festival is a life changing experience where a person can fill the spiritual void he or she experiences in the humdrum of busy urban life. Kumbh Mela is a platform where ordinary men can interact with saints and priests and imbibe the knowledge possed by the latter. It is an opportunity for everyone to dissolve the worldly stresses and flow in the cultural and religious effervescence of the festival. People can get acquainted with the elaborate Hindu rituals that take place during the festival and through association with the saints he or she can understand the significant Vedic principles behind the rituals. The festival is one of a kind and people can take the opportunity to witness this grand event and enrich themselves intellectually, religiously, culturally and introspectively.
Here is one verse from Srimad Bhagavatam {SB}.

Yasyatm a-buddhih kun ape tri-dhatuke
sva-dhih kalatradisu bhauma ijya-dhih
yat-tirtha-buddhih salile na karhicij
janesv abhijnesu sa eva go-kharah [SB 10.84.13]

One who identifies his self as the inert body composed of mucus, bile and air, who assumes his wife and family are permanently his own, who thinks an earthen image or the land of his birth is worshipable, or who sees a place of pilgrimage as merely the water there, but who never identifies himself with, feels kinship with, worships or even visits those who are wise in spiritual truth—such a person is no better than a cow or an ass.
Here cow and ass refer to people with less intelligence because they are going to a place where they will get diamonds but they’ll choose a stone. An ordinary stone has no value in comparison to diamond. Association with a self-realized soul is like owning a precious stone which would make a person more valuable.
Visit the Kumbh mela festival and a take a bath at most auspicious moment in twelve years.
