During meditation, you can see divine dreams, smell divine, taste divine, touch divine, and hear divine Anahata Sounds. God speaks to you and gives you orders. The Kundalini Shakti has been awoken, as shown by these signs. Kundalini has awoken when there is throbbing in Muladhara, when hair stands on its root, when Uddiyana, Jalandhara, and Mulabandha appear involuntarily.

Know that Kundalini Shakti has become involved when the breath stops without effort and Kevala Kumbhaka appears without effort. Know the Kundalini Shakti has awakened when you see waves of Prana coming up to the Sahasrara, when you witness happiness, when you automatically repeat Om, and when you have no thoughts of the world in your head.

When your eyes get locked on Trikuti, the middle of your brows, and the Sambhavi Mudra activates during meditation, realise that Kundalini Shakti has become active. Know that Kundalini has become involved when you sense Prana sensations in various parts of the body, as well as jerks similar to electric shocks. Know the Kundalini has awoken when you feel as if you have no body, when your eyelids shut and do not open to your exertion, and when electric-like currents run up and down the nerves.
