Do not try awakening your kundalini by force. It is a natural phenomenon. Many people go crazy in doing so and ultimately lose their sanity. You should not do that. Meditation happens effortlessly when your kundalini is awakened. Whenever you meditate, you find that scintillating energy flowing all over your being. That is what kundalini is.
When you do the Sudarshan Kriya, every cell becomes awake and alive. The awakening of energy happens very naturally. We should adopt the natural manner only. Otherwise you will lose sleep.
If someone approaches you and tells you, “I will help you awaken your kundalini shakti”, simply thank them respectfully and move away. When a banana ripens on its own it is naturally sweet. If someone forcefully tries to ripen the banana, then it is no longer remains fit for consumption. So, if someone tries to awaken the kundalini shakti by force, there are high chances that one may lose one’s mental balance. Only those who have years and years of practice of yoga and deep knowledge about this can really practice these techniques properly without any side effects.
Unfortunately, today people do not comprehend the sanctity of these powers. Someone learns a few techniques randomly and teaches it to others. They try to awaken the energy with these techniques but without much result; rather it creates more problems. The effect is akin to the fuse blowing up inside a bulb due to an excess and unchecked surge of energy. Some lose their mind, become deranged, or are unable to sleep. We should not try such things at all.
Once a lady visited a mystic, who told her to do certain things. When she did as instructed, she experienced a lot of difficulty and great discomfort. She told me, "Gurudev, I'm not able to go to the temple and my body is not in my control." It should be the opposite way around. You should be able to control even your involuntary system when you do sadhana. When you do wrong sadhana without proper guidance or just by reading books, then the voluntary and involuntary systems get messed up. So you should be careful about this. Key is proper guidance and effortlessness.
The energy should be awakened very naturally and effortlessly. When energy rises naturally and through proper technique, one experiences immense enthusiasm, joy, total belongingness. All these are signs of a true awakening of the shakti (energy). It happens spontaneously when you do Sudarshan Kriya. You feel as if every particle in your body has been infused with energy. That is what the awakening of kundalini is.
