This is the natural organization of human society, the perfect form of social organization, which aims at the material and spiritual well-being of human beings. It is made up of (4) four social classes according to the functions fulfilled by its members, and of (4) four spiritual stages of life.

Why is it absolutely essential to return to the kingdom of God?

Every spiritual being, in their original state, is made to exchange a particular feeling with Krishna, God, the Supreme Personality of Godhead. But to regain the fullness of this primordial state, it is necessary to enter the kingdom of Godhead, because in the material existence in which we evolve, affection is found only in a temporary and distorted form. Only in the kingdom of Godhead is true, absolute happiness found.

The true spiritualist aspires to taste pure emotion in its spiritual form. Living beings on earth are completely ignorant of the true happiness that results from true feelings, true emotions in their absolute purity, as exchanged by holy beings, great pure souls, with Krishna, God, the Supreme Personality of Godhead, in His infinite, absolute, and eternal kingdom.

Exchanges of love are known as “spontaneous devotional service,” offered to Lord Krishna in a feeling of transcendental ecstasy. Lord Krishna wishes to inform all of us conditioned souls that devotional service holds a superior attraction for Him.

Krishna, the Supreme Personality of Godhead, is the reservoir of all kinds of loving exchanges. Full of causeless mercy, He wishes to grant us the privilege of devotional service.

On each of the planets floating in the spiritual world, reigns Narayana, the Supreme Personality of Godhead, as the Supreme Master. There, his devotees possess bodily features identical to his own, and their devotion is marked by a feeling of reverence.

However, beyond all these spiritual planets, there is another planet floating above all others, as large as all the spiritual planets combined, whose name is Goloka or Krishnaloka, where Krishna, the Supreme Personality of Godhead, in His original, personal form, manifests the fullness of His blissful power in free exchanges of love.

This is where all of Krishna's devotees go, offering Him deep and spontaneous love through special devotional service. Indeed, devotional service is the manifestation of the love one feels for Krishna, which we offer Him in a burst of spontaneous affection.

Lord Krishna says to this effect: I respond to the worship of My devotee according to the particular transcendental feeling that animates him; such is My nature.

According to the surrender of men to Me, I reward them in proportion. All follow My path, in one way or another.
