But finding it impossible to do so in the present body any more, it tries to find some vehicle through which it can resume its functions. The pain of the worst stage of the physical disease distracts it more and more so that it thinks it would be more comfortable in any other body than its present one. In confusion, this central force of the astral body enters with that body into the volume of air which fills the physical body, thinking it will gain relief from the unbearable pain. And no sooner the astral body, which is very subtle and finer than the air, enters into it, than it passes out, thus air-encased, through the mouth, causing the death of the physical body. This is the common process of death. Some astral bodies enter the air-body unconsciously if the mind has been benumbed by pain or covered by the influence of excessive Tama. But this is certain of every ordinary soul that it goes out of the body encased in air. The thought predominant in this supreme moment of human life decides the destination of the human soul encased in the astral body when it leaves its physical home. If we think of nothing but of Krishna at this moment we go to Krishna and live in His Abode, Goloka, the Abode of Absolute Love. If we think of Christ we go to Christ in His Father's Kingdom of Heaven. If we are filled with the conception of Nirvāna—extinction of all individuality—we go to Nirvāna. If we desire for higher life above the earth we go to the higher spheres. But if our earthly attachment having their influence on our thoughts at that moment, fill us with regret for being taken away from them or make us desire for earthly life, we return to earth-life again, but not necessarily to a joyful or comfortable life. A life of worldly joy and comfort is due to good Karma and self-denial in some previous existence. A life of sorrow and hardship is due to bad Karma.
