The Alaknanda River flowing past Brahmakapal is considered extremely sacred. Originating near Badrinath, its holy waters are believed to possess purifying powers. Offering Tarpan with Alaknanda’s water directly at Brahmakapal is thought to be highly effective in cleansing sins and granting salvation (moksha) to ancestors. Taking a dip in the river before the ritual is also a common practice for purification. The river’s presence enhances the spiritual potency of the rituals performed on its banks at Brahmakapal
