Kundalini Yoga is the science to unite the finite with Infinity, and it's the art to experience Infinity in the finite. Yogi Bhajan, Oct. 27, 1988
Kundalini Yoga is called the Yoga of Awareness. It is a dynamic, powerful tool that is designed to give you an experience of your soul.
In Kundalini Yoga we harness the mental, physical, and nervous energies of the body and put them under the domain of the will, which is the instrument of the soul. This technology precisely and consciously combines breath, mudra, eye-focus, mantra, body locks, and postures to balance the glandular system, strengthen the nervous system, expand lung capacity, and purify the blood. It brings balance to the body, mind, and soul.
In Kundalini Yoga the most important thing is your experience. It goes right to your heart. No words can replace your experience. Your mind may accept the words or it may not, but your consciousness will not accept just words. Yogi Bhajan, The Aquarian Teacher Training manual
