Yogananda has pointed out the way to union with god is to move in reverse direction through the channel in which we are made manifest.
The yogis say that the meditating devotee on his way to the perception of the Self rises above the consciousness of the world, the senses, and the body (the Vedic rituals) and becomes concentrated on the spinal region and its subtle spiritual centers of consciousness and vital energy (the Vedic esoteric principles). The devotee is then counseled to rise above the perceptions of the coccygeal, sacral, and lumbar regions (corresponding to the three lower Vedas that deal with the material side of life) and to concentrate on the regions of the dorsal, cervical, medullary, and cerebral centers (corresponding to the Rig Vedas, the highest and most spiritual of the Vedas).
