The Dharma Shastras, or treatises on religious obligation, define the samskaras of early infancy as a collective term (dharma).
Jatakarma (birth rituals),
namakarana (name),
nishkramana (first excursion),
annaprashana (first feeding),
chudakarana (tonsure),
and karnavedha are examples of these rites (piercing the ears).
The text's main aim is to demonstrate the significance of the Pushti Marg, especially the influence of the Pushti Marg's leaders on these eightyfour holy figures, which are held in almost every Hindu community.
It's a fascinating sectarian work, but it's not historically accurate.
