Jīvanmukti is possible only after nirvikalpa samādhi, because it destroys vāsanās in avidyā.

Since deha of the jnAni is avidyAkruta, even after attaining the paramArtha jnAna, if he continues to live in the present deha due to prArabdha, it is a clear sign that he is having the avidyA lesha. So either he should experience the state of nirvikalpa samAdhi where he goes beyond dehAtma buddhi or he has to die ( literally getting rid of physical body) to ‘experience’ the state of real mOksha / mukhya mukti. And as per some school due to this association of BMI, the jnAni’s Jeevan mukti is considered as gaUNa mukti a second to ultimate Videha mukti. Arguments in post-shankara works are more or less like this.
Hari Hari Hari Bol!!!
