Deep and fast breathing is bound to have a profound effect on the kundalini. And all the centers, which you call chakras, are nothing but halting places for the kundalini on its journey's way. These are the centers through which the kundalini passes. Ordinarily there are any number of such centers, and there are different estimates of them. But broadly speaking there are seven important centers where the kundalini, while moving up and down, is likely to halt and rest for awhile. And it will have its effect when it comes in contact with them. And its first effects will be felt on the center which is your most active center as such. For instance, if a person constantly works with his brain, then with deep breathing his head will become very heavy. It will be so because his brain center happens to be his most active center. The first impact of breathing will be felt on his head, his active center, and it will become heavy. And if a person is sexual, his sex center will be stimulated in the first instant. Similarly a loving man will find his love stimulated, enhanced and flowing. And if one is emotional, his emotions will be heightened.

So the most active center will be hit and stimulated first by deep and fast breathing. But very soon it will begin to affect other centers too. And accordingly a change, a transformation of the personality begins simultaneously. You will begin to know that you are changing; you are not the same person that you were up to now.

We don't know that there are very many possibilities within each one of us. We are familiar with only that center of ours which is active and dominant and where we exist. So when another center opens up it seems that our old personality is gone and a new man has appeared in its place. Or it seems we are now not the same as we were before. It is like this: I am aware of only one room in a house where I live, and I carry the imprint of this room in my mind. And suddenly one day a door opens and another room appears before me. Then my whole mental map of the house will undergo a change. Now the house that I had thought to be mine will be a very different house, and I will need to arrange it anew.

So as the various centers will be hit and activated, new dimensions of your life will begin to unfold and manifest themselves. And when all the centers will be active together -- that is, when energy will flow through them all uniformly -- then for the first time we will live a whole life; we will live totally.
