On the soul's need for freedom ...

The self [soul] is beyond the gross body and subtle mind. He is the potent active principle of the body and mind. Without knowing the need of the dormant soul, one cannot be happy simply with emolument of the body and mind. The body and the mind are but superfluous outer coverings of the spirit soul. The spirit soul's needs must be fulfilled. Simply by cleansing the cage of the bird, one does not satisfy the bird. One must actually know the needs of the bird himself.

The need of the spirit soul is that he wants to get out of the limited sphere of material bondage and fulfill his desire for complete freedom. He wants to get out of the covered walls of the greater universe. He wants to see the free light and the spirit. That complete freedom is achieved when he meets the complete spirit, the Personality of Godhead. …The hankering soul must be satisfied by the perfect scientific process of perfect devotional service.
