Penetration Into Intelligent Infinity Level

[Infinite]

Another good stretch from the book "Realizing God: Lectures on Vedanta" by Swami Prabhavananda:

Sri Ramakrishna summed this up from his own experience in a few words. He said that the kundalini, the Mother energy, lies asleep at the base of the spine and that an individual ordinarily lives within the three lower centers: at the base of the spine, the root of the genitals, and the navel. As such, no higher thoughts, no pure thoughts, come, but attachment to worldliness - lust, greed, and power - remains. When spiritual awakening comes, consciousness is in the region of the heart. There one has the vision of God as formless, blissful light, and wonders at the beauty, the grandeur, and the great joy of that experience. Then when reaches the next higher center in the region of the throat, that person becomes completely detached from worldliness and cannot bear worldly talk; the mind dwells in God. When the kundalini rises to the next higher center between the eyebrows, ecstasy is attained, and samadhi, a complete vision of God. But there is still a sense of duality, the sense of "I." The supreme truth of Brahman is experienced, but there is a thin glass partition, as it were. When that partition is gone and the kundalini becomes united with Shiva in the center of the brain, the individual experiences unified consciousness. Of course this experience is indescribable and indefinable.
