Namjap ji,
Though the question is not directed to me yet I think to offer a small clarification. Kundalini jagran through breath control was widely practiced by yogis and sidhas. Many
Sikh- preachers still tell these things in the context ot Sidh Ghosthi. There are many recordings available on the net.
Kudalini awakening leads to release of energy. By following the method of breath control, called Pranayaam also, it takes lot of time as one has to start from the lowest most chakra called as mool chakra. It is from this that one graduates to the highest level to crown chakra.
Sikhism has not approved of it; instead it is recommended the Naam practice and it is stated in bani that one can have the kundalini awakening by 'naam' and by eulogizing the Creator through keertans etc. in the sangat.
This kind of raj yog was recommended by Swami Vivekanand as well but sikhs do not practice it as a part of religion.One may do it for the purpose of mantaining good health etc.
