If kundalini moves and there are no blocks, then you will never feel any chakras. That is why someone may feel nine chakras, someone else may feel ten chakras, and someone else may feel only three or four, or one, or none. It depends. In actual fact, there are infinite chakras and at every movement, every step of the kundalini, a chakra is by the side to help. If the help is needed, it can be given.
That is why I insist that a theoretical acquaintance is not helpful. And meditation as such is not really concerned with kundalini at all. If kundalini comes, that is another thing – but meditation has nothing to do with it. Meditation can be explained without even mentioning kundalini; there is no need. And by mentioning kundalini it creates even more conflicts to explain the thing. Meditation can be explained directly; you need not bother about chakras, you begin with meditation. If the passage is blocked you may come to feel kundalini, and chakras will be there, but that is completely nonvoluntary. You must remember that it is nonvoluntary; your volition is not needed at all.
The deeper the path, the more nonvoluntary. I can move my hand – this is a voluntary path – but I cannot move my blood. I can try. Years and years of training can make a person capable of making blood circulation voluntary – hatha yoga can do that; it has been done, it is not impossible, but it is futile. Thirty years of training just to control the movement of the blood is meaningless and stupid because with the control comes nothing. The blood circulation is nonvoluntary; your will is not needed. You take food and the moment it goes in, your will is not needed: the body machinery, the body mechanism, has taken over, and it goes on doing whatever is needed. Your sleep is not voluntary, your birth is not voluntary, your death is not voluntary. These are nonvoluntary mechanisms.
Kundalini is still deeper, deeper than your death, deeper than your birth, deeper than your blood, because kundalini is a circulation of your second body. Blood is the circulation of your physiological body; kundalini is the circulation of your etheric body. It is absolutely nonvoluntary; even a hatha yogi cannot do anything with it voluntarily.
One has to go into meditation, then the energy begins to move. The part that is to be done by you is meditation. If you are deep in it, then the inner energy begins to move upward, and you will feel the change of flow. It will be felt in so many ways: even physiologically the change can be known.
For example, ordinarily, biologically, it is a sign of good health for your feet to be warm and your head to be cool. Biologically it is a healthy sign. When the reverse occurs – the feet become cool and the head becomes warm – a person is ill. But the same thing happens when the kundalini flows upward: the feet become cool.
Really, the warmth in the feet is nothing but sex energy flowing downward. The moment the vital energy, the kundalini, begins to flow upward, sex energy follows. It begins to flow upward: the feet become cool and the head becomes warm. Biologically it is better for the feet to be warmer than the head, but spiritually it is healthier for the feet to be cooler because this is a sign that the energy is flowing upward.
