Through meditation the seminal energy is transformed into ojas or creative energy. The very source of energy, the kundalini shakti, is awakened in the meditator by the virtue of meditation. This ojas manifests in him as divine wisdom (jnana shakti), will power (iccha shakti) and creativity (kriya shakti).
As the flow of the sex energy is turned upward, this fire of kundalini cures all his physical and mental illnesses and makes him healthy and happy. His body shines like molten gold, and one can see the yellow, blue-colored rays springing from his body, bringing healing to humanity.
