The Lord descends into the material universe to save us.
Krishna appeared on the surface of this globe, the earth, in order to reduce the burden of the world, destroying kings who needlessly increase their military forces. He is the refuge of submissive souls, the Sovereign Benefactor of the simple and the humble. Let us take refuge in Him, so that He allows us, Him alone, to escape the labyrinth of material existence.
Lord Krishna, God, the Supreme Person descends in our galaxy as in other galaxies at intervals regular, to re-establish the spiritual culture that time is declining. The Lord appeared 5,000 years ago to regenerate spirituality, but also to manifest His divine entertainments, and to draw to Himself the fallen souls that we all are, so that they return to their original home, in the kingdom of God.
Krishna is so fascinating, so beautiful and so powerful, that He draws all living beings to Himself. For example, the Lord captivates the mind thanks to the scents emanating from the flowers offered to Him, to his spiritual entertainment, to his personal beauty and his bodily features, to the sublime spiritual sound vibrations that He brings out of his flute, or by its sublime qualities and activities. When He appeared in Vrindavana, a region of India, He drew to Himself, besides human beings, animals, plants, trees. All were drawn out of love and affection for the Lord.
Krishna, God, the Supreme Person, descends into this material world, our galaxy or other galaxies at regular intervals, to call fallen souls to Himself, souls embodied and conditioned by matter and the energy of illusion, and to bring them back to their eternal home, where again they will live eternally with Him.
To save these souls, Krishna sometimes comes Himself in his original form, or in various other forms, such as Avatars. Sometimes again, He dispatches his intimate servants, his sons, his companions or even his representatives.
The Lord says: I remain unborn, and My transcendent body does not decline. I am the Lord of all beings, and yet in My original spiritual form I descend into this galaxy [the Milky Way] at regular intervals.
Whenever in any place of the universe spirituality sees a decline and irreligion arises, I descend in Person
Although the Supreme Lord is unborn, He continually appears under his personal and original form of Krishna, or in various forms of Avatars. Since Avatars are eternal, so are their activities. All of the Lord's activities are purely spiritual, and free from the taint of the attributes of material nature. His entertainments are for Him a source of transcendent bliss. The appearances of the Lord in this world are infinite, and his manifestations are all, of knowledge, of bliss and of eternity.
By his teaching, the Lord intends to free human beings from ignorance to which the Lord has reduced them. material existence.
