Logos 189
The Lord said: “The being who fulfills his duties in a spirit of detachment, without any sense of possession and devoid of false ego, (who does not identify with his body) regains, through a total purification of his consciousness, its original, natural and eternal condition; thus indulging in apparently material acts, he can easily enter the kingdom of God”.
All beings who have come into this world are animated by a spirit of domination. The being absorbed in the practice of devotional service in full awareness of God does not claim any right of ownership over what surrounds him, nor does he think, under the influence of the false ego, (which consists in identifying one's body and forget to be a spiritual soul) to be God or the absolute master. He always sees himself as a servant; such is indeed the way which allows to purify the conscience. However, only a pure conscience allows one to enter the kingdom of God. Materialists, on the other hand, can always, at the height of their glory, reach such and such a planet in the material universe, but all are subject to repeated destruction.
Logos 190
It is written: “According to his self-interested acts, the conditioned being obtains an appropriate body, with material mind and senses. Then, the consequences of these acts end and this is called death; and when a new set of karmic reactions begins, then birth occurs”.
From time immemorial the conditioned incarnate being passes from one living species to another, from planet to planet, in a movement for so to speak perpetual. All beings in this world roam the universe on the vehicle of the body, offered by material energy through specific parents. Material existence is based on a series of actions and reactions. When a child is born, it is important to know that the particular body he has put on corresponds to the beginning of a new series of acts, and when an old man dies, it is because a set of karmic reactions has just ended. We can see that due to their different karmic activities, an individual will be born in a rich family and another in a poor family, one will suffer while the other will have a happy life, although they can both be born in the same place, at the same time and in the same environment. Whoever takes with him the fruits of acts of virtue obtains a rebirth in a wealthy or pious family, when the one who drags behind him ungodly, guilty or even criminal acts must be reborn in an unfortunate or inferior family. To change the body is to change its field of action.
It is clear that a specific body form is attributed to the spiritual being according to a particular category of activity. And this process repeats itself continuously.
