Excerpts from KRI Aquarian Teacher Training Manual Level One Textbook:
“I felt people in the West needed the kind of [yoga] system that could give them positive understanding and awareness in no time. That system had to be solid and practical enough so any head of the family could practice it. I don’t know better system than Kundalini Yoga.
The beauty of Kundalini Yoga is that if you can just sit physically, set the automatic rhythm of your pranayam (breath control) and add a creative naad (inner sound), your mind is focused and balanced. In a kriyā you can immediately strike a complete physical, mental and spiritual balance. It works so efficiently and quickly because of this fullness, balance and energy.
Since any method, from prayer to dance, to help you achieve Universal Consciousness must eventually elevate your kundalini to achieve it, why not start directly with Kundalini Yoga? Kundalini Yoga is a direct, fast and perfect practice for the rhythm of a modern home.
It’s hard to teach Kundalini Yoga. A teacher who doesn’t have a ray of energy within himself can’t teach it. That’s the first foundation. As a master of Kundalini Yoga, you must set yourself at a certain level of consciousness to take people to that level. If you don’t have that bond of consciousness, Golden Bond and spark or conscience, then you can only instruct in the dark.
That’s the problem. You could come and I could give you a lot of powerful and elegant exercises. You’d feel good. However, when I talk about life and humanity, and the sum total of existence and awareness, you have to feel that magnetism comes from me. My confirmed reality and conscience must be present to act as a guide and compass. If I can’t give you that, there’s nothing to take you to that new level. Kundalini Yoga is the master science of experience and awareness. It’s a person-to-person conscience transmission. It’s a Raj Yoga that wakes you up inside.”  ~the Siri Singh Sahib, Yogi Bhajan
