Teachings on death in Dnyaneshwari from chapter 8
He who becomes one with Me (Bhagavan or God) from outside as well as inside, sheds the layers of the five principles from his body automatically. He who is not aware of his body even while living does not feel grief from death. A vessel immersed in water has water inside as well as outside. Does water break if the vessel breaks? Similarly even if body gets destroyed, Brahman (God) continues to be everywhere and therefore how can the intellect which has become one with it get destroyed? Therefore those who remember me (Bhagavan) at the time of death become one with me. (8:59-68)
The normal rule is that after death a person attains that state which is in his mind at the time of death. He cannot avoid it. Just as one dreams of things which are constantly in the mind while awake, whatever one longs for in life comes to the mind at the time of death and he attains that state. Therefore make a habit of always remembering Me (God). Consider that whatever you hear, think, see, speak is Me throughout, then I am always with you. I assure you that if you offer your mind and intellect to Me then you will attain only Me. If you any doubts about this then experience it by practising it. (8:69-80)
Purify your conscious mind by this practice and lead it to the spiritual path. If the mind, which takes one here and there, gets engrossed in Brahman then who cares or remembers whether the body exists or not? The mind merges with Consciousness which is solid bliss. (8:81-85)
With the knowledge that the faultless Brahman is formless and without birth and death, that It witnesses all, is older than the sky and subtler than the atom, that the affairs of the world go on by association with It, that It gives birth to all the visible world, that the world lives by It, that It is beyond logic and beyond imagination, that eyes cannot see It even in broad daylight, that like a sunbeam It always appears lustrous to men of Knowledge, that It never sets, he (a person of Self-realisation) who concentrates on It with steady mind at the time of death while outwardly, sitting in the lotus position facing north, with the eternal bliss gained by practising desireless actions (Karma Yoga), with the love of Self-realisation and using the yogic techniques mastered for attaining it quickly, he brings the life-force (Prana) from the centre (Chakra) of fire or energy (i.e. Manipura Chakra near the navel) through the central nerve i.e. the Sushumna route to the Brahmarandhra or aperture on the crown, where the life-force merges with the sky-principle.
The immobile mind and the life force appear outwardly to have merged. But because the mind has become stable and devotion steady, and with the strength of the yogic power, that life-force eliminates the movable; and then the immovable enters the centre of the eyebrows and vanishes there. Just as the sound of a bell vanishes in the bell itself the devotee leaves his body and merges into pure Brahman which is my lustrous form. (8:86-99).
