wherein it is said, patanty adhaḥ, which means “they again fall down.”
The monist philosopher, after executing severe austerity,
merges into the impersonal effulgence of the Lord,
but the living entity always wants reciprocation in loving affairs.
Therefore, although the monist philosopher is elevated
to the status of being one with the effulgence of the Lord,
because there is no facility for associating with the Lord and rendering service unto Him,
he again falls into this material world, and his service propensity is satisfied
by materialistic welfare activities like humanitarianism, altruism and philanthropy.
There are many instances of such falldowns,
even for great sannyāsīs/renunciants in the Māyāvāda/all is illusion school.
