The motionless flame of a lamp

on the attainment of the fifth state, the mind of the seeker ceases, like clouds in an autumn sky, and only truth remains. in this state, wordly desires do not arise at all. During this state all thoughts of division in seeker are stilled and he remains rooted in non-duality. on the disappearance of the feeling of division, the fifth stage, known as the sushuptapad--sleeping, draws the enlightened seeker into its nature. he is perpetually introverted and looks tired and sleepy, even though externally he continues his everyday activities.
on the accompaniment of this stage, the desire-free seeker enters the sixth one. both truth and untruth, both egoism and egolessness and all sorts of mentation cease to exist in this state, and rooted in pure non-duality, the seeker is free from fear. as teh entanglements of his heart dissolve, so all his doubts drop. this is the moment ehen he is completely emptied of all thought. without attaining nirvana, he is in a nirvana like state and becomes free while yet dwelling in the body. this state is like that of the motionless flame of a lamp.
and then comes the seventh stage.
