An analogy of emptying oil from vessel is cited here. Even after emptying, there'll be little stain on the vessel.
Here the difference between even man & woman ceases to exit & the sthitaprajña sees only the nitya-shuddha-Atma everywhere at all times

Same as (A), except that his apraroksha-jnana takes a strong root & becomes unshakeable
