It all depends upon the degree of purity, stage of evolution, the degree of purification of
the Nadis and the Pranamaya Kosha, and the degree of Vairagya and yearning for liberation.
A student starts his Sadhana from the point or stage he left in his previous birth. Some
are born with account of purity and other requisites of realization on their having undergone the
necessary discipline in their past life. They are born Siddhas. Guru Nanak, Jnana Dev of Alandi,
Vama Dev and Ashtavakra were all adepts from their very boyhood. Guru Nanak, when he was a
boy, asked his teacher in the school about the significance of OM. Vama Dev delivered lectures
on Vedanta when he was dwelling in his mother’s womb.
