Kundalini Yoga: Beneficial or Dangerous?
Sadhguru: In the yogic culture, the snake is a symbolism for kundalini – the unmanifest energy within you. The nature of kundalini is such that when it is still, you do not even know it exists. Only when it moves, you realize there is so much power within you. Till it moves it is almost non-existent. Because of this, kundalini is symbolized as a snake because a coiled-up snake is so hard to see unless it moves. Similarly, you do not see this coiled-up energy unless it moves. If your kundalini is aroused, miraculous things that you cannot believe possible will happen with you. An unleashing of a completely new level of energy begins and your body and everything behaves in a completely different way.
Kundalini and perception
Heightened states of energy are also heightened states of perception. The whole yogic system is aimed only towards enhancing your perception. A spiritual process essentially means just that – to enhance your perception because you know only what you perceive. This is the reason for the symbolism of Shiva and a snake. It indicates that his energies have reached the peak. His energies have reached the top of his head and so his third eye has opened.
