Lord Krishna says, At the moment of death, the soul takes a new body, as naturally as it passed through the previous one, from childhood to youth, and then to old age. This change does not disturb the sober being.

Unfortunately, this spiritual education is completely absent from today's civilization. No one knows their true interest, which is that of the spiritual soul that each of us truly is, and not that of the material body, which is in reality a garment we have donned.

It is the interest of the soul that must be sought, not that of the body. It is the needs of the soul that must be satisfied, not those of the body.

Working intensely under the influence of a bodily conception of existence, without spiritual education, is tantamount to living like an animal. People expend so much energy simply for the convenience of the body, without being instructed as to the benefit of the spirit soul. They thus live in a dangerous civilization, for the spirit soul must indeed reincarnate from one body to another.

Without spiritual education, people are kept ignorant of the facts relating to God as He really is, their true spiritual identity, true eternal spiritual knowledge, and existential and absolute truth, and do not know what will become of them after the death of their body. They work blindly, and blind leaders direct them.

Man deprived of reason does not know that he remains completely enslaved by material nature, and that the latter will impose upon him after death a certain type of body that he must accept, whether he likes it or not. He doesn't know that although he may be someone very important in his current material body, he risks being reborn in the body of an animal or even a tree for having acted in ignorance of God, under the influence of ignorance, one of the three attributes and modes of influence of material nature.

Spiritual education cultivates and develops God-consciousness and gives humanity the true transcendental light of spiritual existence. It teaches that each of us is truly an eternal spirit soul and not the material body with which we wrongly identify, and teaches us to surrender to Krishna, the Supreme Personality of Godhead, to renew the bond of love that unites us with Him, to link our desires, interests, and plans to His, to love Him, to obey Him, to do His divine will with great joy, and to serve Him with love and devotion.

Such is the perfection of existence.
