In the fourth stage of "Satvapatti", the liberated Yogi, by ripening of the practice of "Nirvikalpa Samadhi", loses the ego (or I-ness) about and attachment (or my-ness) for the body etc., and enters the fifth stage of "Asamsakti", which is also known as "Brahmavidvara." In this stage, like a being in deep slumber or "Sushupti", the Yogi or "Jnani" remains without any "Asakti" (desire + attachment) for the "Jagat" or this physical creation / universe.
In this stage, the "Buddhi" or intellect gets firmly established in "Satva" or equanimity. So, don't confuse this "Jnanic" stage with just deep sleep, which is a result of "Tamas" or lethargy. The comparison with "Sushupti" or deep sleep is made to highlight that the intellect becomes still, as opposed to "Buddhi" or intellect which is non-still during "Jagrat" (waking) or "Svapna" (dream) states. In Sushupti, the senses get completely withdrawn from sense-objects. Similarly, in "Asamsakti", the liberated Jnani, having withdrawn all his senses from their respective sense-objects, dwells in this world with one-pointed intellect.
What is that one-pointedness? It is the one-pointedness in "Brahman", in the sense it sees Brahman in everything, it sees Brahman everywhere, it sees Brahman at every moment in time. Let's get into it through the concept of "Dvaita" or duality vis-a-vis "Advaita" or singularity. In "Dvaita", one sees ear-rings, necklaces, engagement rings, bracelets, etc. In "Advaita", one perceives gold underneath the aforementioned ornaments. Similarly, in "Dvaita", the world is real, and you have an Obama as President, or a Gates as the richest man in the world, and you also have the John Edwards and the John McCains in politics, and you also have the homeless begging: "Why lie, need beer." In "Advaita", you see the underlying spirit animating all these different "successful" and not-so successful beings. This underlying spirit is not a sense-object, hence the aforementioned illustration of "Sushupti" where perception of sense objects is not there is given...Alongside perceiving God or Brahman as true, this world or "Jagat" is perceived as false, full of sorrow and suffering, and consequently perceived as "worth rejecting" by the YOGI or JNANI who is in the "Asamsakti" stage. This stage onwards, the Yogi is considered to be liberated-while-living (Jeevan Mukta), and enjoys the great bliss of one's own self (Atman) which is is homogeneous, ever full, without deformation, without movement (being everywhere), etc.
