"Lastly, the seventh centre, the most important centre is the Sahasrara which has got, according to Sahaja Yoga, a thousand petals. Actually there are a thousand nerves and if you cut the transverse section of the brain you can see that all these petal-like structures of the brain are forming a lotus of the thousand petals. This centre of a thousand petals covers the limbic area of the brain before Realization like the closed bud of a lotus. Above this covering is the balloon-like structure of ego and superego. As the brain is covered completely when these two institutions join and calcification takes place on top of the head; that is how we become a closed personality. At the time of our awakening, of our second birth, this egg-like personality breaks at the top of the head."
--H.H. Shri Mataji Nirmala Devi
The Sahasrara Chakra encompasses the crown of the head where all Chakras of the subtle system are integrated. When Kundalini passes through the top of the head, at the fontanel area, your Realization is manifested. Sahasrara is the Promised Land where absolute freedom and Truth is granted.
Deity
The presiding Deity of the Sahasrara Chakra is Shri Lalita Devi. Her first ever complete manifestation on Earth is in the human form of Shri Mataji Nirmala Devi. Through Her Grace our Kundalini is awakened, our spirit is enlightened, and we feel the Paramchaitanya also.
Quality
At the point of the Sahasrara we go beyond the relative to the Absolute, and into the Absolute realization of Heaven on Earth. This is a country far beyond our wildest imaginings, so much more than our words can even seek to imply. This is our ultimate destination, stretching out forever. Our progress towards this goal is a living process. When the seed matures it naturally sprouts. When the Kundalini reaches the Sahasrara, the lotus petals open and enlightenment takes place. You may feel a pulsation in the crown of the head, followed by a melting sensation and a flow of cool vibrations from the fontanel areas. This is the baptism by which you know that you are truly born again.
Vibratory awareness begins at this point. As the Kundalini unites our individual consciousness with the Universal Consciousness (the Atma to the Paramatma), we are suddenly tuned in to the Universal Wavelength of Vibrations. These vibrations pervade the cosmos but before Self-Realization, while we are still in the ego form, we know nothing of them. When the Kundalini breaks the shell of the egg, we emerge in His Kingdom, the Collective Unconscious. Very ancient and great realized souls, liberated from the physical body ages ago, are now able to reach this Kingdom of God within effortlessly. By taking birth again on this Earth they are living proof to the human race that they are pure spirit within, and all capable of attaining eternal life. "But the man who is ignorant, who has no faith, who is of a doubting nature, perishes. For the doubting soul there is neither this world nor the world beyond nor any happiness" (BG 4:40). We must have a positive basis for life, an unwavering faith to discover the Truth which stands the test of life. "Kill therefore with the sword of wisdom the doubt born of ignorance that lies in thy heart. Be one in self-harmony, in Yoga, and arise, great warrior, arise!" (BG 4:42).
As human awareness is united to the Divine, we move into the subtlest of communication, that is, into Collective Consciousness. We begin to feel the presence and guidance of His Spirit within us and in others as well. We learn to appreciate the real depth and beauty of another person through vibrations. The beauty of Nature now manifests itself as vibrations. Just ask the question and a positive answer comes as a flow of vibrations. It is conversation with the Universe at its most sublime.
