Jai Sri Baba Lal Ji,
Know for sure that death is a passing from gross plane to subtle reality where Atman remains bare from gross body but possesses mind intellect and ego, but with time all the three features faded in itself and smrati takes roots separately in kamic baggage to relate the next,
Breathing reality and breathing patterns speaks a lot about the theory and practice of this inherent process of transmigration, as long as smrity exists mind remain active and may create havok for atman in quest of belongings of past and lineage,
But in majority of cases, smarati cease to exist within next thirteen days of transition, in rarest case it last for a year, Only supreme Brahman whether as incarnated or without that his smriti remains intact both ways since inception of this universe and even after dissolution,
Suffering of soul after death resort to active smriti alone nothing else, once it cease to Atman reaches ar parabolic state of least conscious with more peace til next amalgamation with a body through a womb or one among four,
Jai Baba Lal Dayal Ji,
