Ma Yoga Shakti 
The Invisible Seven Psychic Lotuses: 

The psychic lotuses reveal different stages of human evolution. We are born as a mortal with weaknesses, but nature preserved our dormant faculties. These dormant faculties can be developed by systematic techniques of meditation. Humans live in two bodies and in two worlds simultaneously. The material world and body, and the psychic world and body. The psychic world and body can only be approached by withdrawing awareness from the wakeful world. The seven psychic lotuses are seven gateways to the unseen world of awareness. The round form of a flower is a spiritual symbol and the lotus form is projection and manifestation of the spiritual symbol. The illustrations are how Ma Yoga Sakti meditated on the chakras and commissioned an artist to paint them. They are for meditation to arouse the kundalini power and psychic faculties. They also may be used as decorative pieces for a shrine or yoga hall. In the e Book format this book may be best used on a tablet that can display the pictures in color. Meditate on the psychic lotuses pictures, one by one. 1. Meditate on each lotus for three months. 2. Localize the lotus on your spinal chord. 3. Feel the internal nerves vibrating. 4. Feel your endocrine glands pulsating, stimulated by the lotus meditation. 5. After twenty-one months meditate on the threading process of the lotus, known as chakra bedan or padma chhedan kriya.This is the surest, purest and highest form of kundalini yoga which cannot be classed with lower forms of tantra. Consciousness is supreme. It functions through the nerve centers of the body
