Friends, yoga is a scientific method. Common people cannot understand it easily. They will practice it when they understand it. That is why the Puranas have been composed to facilitate the common public. Yoga has been explained in the Puranas as various mythic events and stories. Although being as mythological forms these stories are still theoretically true. This is so because these myths are classical and specially designed, as opposed to non classical or ordinary myths. Contrary to the thinking of some so-called modernists, they do not fall under the category of superstition. Many things cannot be said directly to avoid violations of social, personal and practical limitations, hence they have to be said as scientific myths. Yoga can be difficult to understand instantly. One has to adopt a Yogic or nondual lifestyle for a long time. That is why in Puranas, things related to yoga are presented as amusing mythology. This keeps these stories interesting for a man for a long time. With this, a man automatically becomes a yogi indirectly, and with a little extra effort, he can also become a perfect yogi if he gets a favorable situation. If everyone became a fulltime yogi together, then how would worldly work go. That is why yoga is molded as such scientific and pleasant stories, on which faith remains. Due to this, the man remains tied in the Yogic lifestyle at all times even while performing all the obligations of worldliness. One such famous story comes in the Shrimad Bhagwat Mahapuran, which describes the war between Lord Krishna and Kaliyanag. According to that legend, a huge snake named Kaliya who had hundreds of hoods lived on the island of Ramanak, with the fear of Garuda, the vehicle of Lord Vishnu. He was cursed by some saint that Lord Krishna will kill him and liberate him. Therefore, he came to the river Yamuna flowing near Vrindavan. The water of the Yamuna became poisonous due to its poison, killing the people, birds and animals around. Lord Krishna was playing ball with his grazer friends. Then his ball went into the water of Yamuna. Shri Krishna immediately leaped into the Yamuna. The next moment he was wrestling with Kaliynaag. After a lot of trouble, Shri Krishna climbed on the middle and biggest head of it. There he increased his weight and mashed his hoods. He grabbed his head and tail together and hit him here and there. In the end, he forced Kalyanag to give up. Then Kaliyanag’s wives came there and started asking Lord Krishna for his life. Srikrishna left him on the condition that he along with his family would leave the Yamuna and return to the island of Ramanak and would never enter the Yamuna again.
Kaliyanag is a symbol of the sushumna nadi or spinal cord, and Lord Shri Krishna is the symbol of Kundalini
In fact the structure of man resembles a serpent. The man’s software is made up of his central nervous system, which looks like a hood raising snake in shape. The brain and spinal cord come in it. The rest of the man’s body has been overlaid on this central nervous system. Sushumna channel runs in this central nervous system. Here the water of Yamuna river symbolizes the cerebrospinal fluid flowing around the spinal cord. Living in the island of Ramanak is a symbol of worldly indulgence. The word Ramanaka is derived from the Sanskrit word Ramanika or ramaneeya, meaning amusing. The fear of Garuda symbolizes the fear of saints. Saints do not go to the indulging places. It is seen that saints keep people away from unnecessary conflicts of worldliness. The curse of a monk means to show the right path to God by a gentleman. Saying about Kaliyanag being killed by Shri Krishna is a symbol of liberating him from the bondage of attachment. Shri Krishna sending him back to the island of Ramanak means that he should go in seclusion away from the innocent people of the world and spread poison of attachment there. Kaliyanag’s wives symbolize the ten senses. There are 5 work senses and 5 knowlege senses in them. These senses are said to be the wives of Kaliyanag because they become very powerful in the connection with the man attached to the world and become one with him. The poison of Kaliyanag signifies a attached lifestyle. It is the most powerful poison in the world. Due to this, man keeps dying in the cycle of birth and death again and again. The poison emanating from hundreds of hoods of Kaliyanag means that this attachment keeps on growing due to the hundreds of desires and worries that arise in the brain. Lord Krishna is the symbol of Kundalini here. His climb to the central hood of Kaliyanag means meditating Kundalini in the Sahasrara Chakra. Playing ball by Sri Krishna means Kundalini Yogasadhana. The ball is a symbol of pranayama here. Boy Krishna’s friend grazers symbolize various types of pranayamas and yogasanas. Breathing in and out denotes the ball going back and forth or up and down. The entry of the ball into the river means the entry of pranavayu into chakras. Sri Krishna’s leap into the river means that Kundalini also entered the chakras with pranavayu. Yamuna is the holy river in which Sri Krishna jumps. This means that the Kundalini enters only in the chakras consecrated by breathing. Mulling of the Kaliyanag by Sri Krishna means that Kundalini has curbed the mind’s unnecessary desires and concerns, and has cleaned up the ideological waste buried in the subconscious mind. The holding of Kaliyanag’s head and tail together by Sri Krishna means that the Kundalini has spread across the entire Sushumna channel from Muladhara Chakra to Sahasrara Chakra. Taking power from the Muladhar, Kundalini is shining in Sahasrara. This happens when the palate-tongue joint or Sahasrara and Muladhara are meditated together. By doing this, Kaliyanag’s banging means that the unnecessary noise of the brain is being eliminated, due to which man is moving towards eternal joy. To attempt to kill Kaliyanaag means to let the central nervous system of the body function in a controlled manner. Kaliyanag’s non-entry into the Yamuna again means that after Kundalini awakening, man never behaves indulgently.
