Indian culture in fact all ancient cultures over the world are full of mysterious and incredible sciences and knowledge. Samadhi and Mahasamadhi are one of them.
What is Mahasamadhi ?
According to Shaiva tantra of Hinduism the divine feminine energy is located at the kundalini of every individual and when one perform kundalini yoga this divine energy awakens. The kundalini yoga has defined seven chakras.
One has to practice Kundalini Yoga to clear all these chakras. Once you reach and clear the topmost chakra SAHASRARA , where knowledge blooms like a lotus, one attains Samadhi in which one’s soul consciously leaves the body to roam around the world.
The concept of Mahasamadhi is even higher than Samadhi. In MAHASAMADHI one voluntarily leaves the body and unite with Paramatma, the ultimate GOD. According to Yoga scriptures when a Yogi attains Samadhi or MAHASAMADHI his soul passes out through SAHASRARA which causes the blood to flow out from nostrils.
Have any human attained Mahasamadhi ?
It is believed that Indian monk Swami Vivekananda has attained Mahasamadhi. On 4 July 1902 Swami Vivekananda after 9 pm when his disciples entered his room he was lying on his bed with beads of perspiration on his forehead. He cried like a baby and took few deep breaths and then a little blood came out of his nostrils. His head shook and fell off the pillow and his eyes became still. But after all this there was smile on his lips and as described by his disciples an unearthly glow was emitting from his smiling face. Medical science said that he had a heart attack or a blood vessel in his brain ruptured but his disciples believed that his vein ruptured as his brahmarandhra (an opening in the crown of his head) got pierced when he attained Mahasamadhi.
Though we have almost lost the science of kundalini yoga today but we know that there exists a high level of consciousness through which we can become one with the almighty.
