No theoretical knowledge is helpful. When you have some theoretical knowledge, you begin to impose it on yourself. You begin to visualize things to be the way you have been taught, but they may not correspond to your individual situation. Then much confusion is created.
One has to feel the chakras, not know about them. You have to feel; you have to send feelers inside yourself. Only when you feel your chakras, and your kundalini and its passage, is it helpful; otherwise, it is not helpful. In fact, knowledge has been very destructive as far as the inner world is concerned. The more knowledge gained, the less the possibility of feeling the real, the authentic, things.
You begin to impose what you know upon yourself. If someone says, “Here is the chakra, here is the center,” then you begin to visualize your chakra at that spot; and it may not be there at all. Then you will create imaginary chakras. You can create; the mind has the capacity. You can create imaginary chakras, and then, because of your imagination, a flow will begin that will not be kundalini but will be simple imagination – a completely illusory, dreamlike phenomenon.
Once you can visualize centers and can create an imaginary kundalini, then you can create everything. Then imaginary experiences will follow, and you will develop a very false world inside you. The world that is without is illusory, but not so illusory as the one you can create inside.
All that is within is not necessarily real or true, because imagination is also within, dreams are also within. The mind has a faculty – a very powerful faculty – to dream, to create illusions, to project. That is why it is good to proceed in meditation completely unaware of kundalini, of chakras. If you stumble upon them, then it is good. You may come to feel something; only then, ask. You may begin to feel a chakra working, but let the feeling come first. You may feel energy rising up, but let the feeling come first. Do not imagine, do not think about it, do not make any intellectual effort to understand beforehand; no pre-notion is needed. Not only is it not needed, but it is positively harmful.
And another thing: kundalini and the chakras do not belong to your anatomy, to your physiology. Chakras and kundalini belong to your subtle body, to your sukshma sharira, not to this body, the gross body. Of course, there are corresponding spots. The chakras are part of your sukshma sharira, but your physiology and anatomy have spots that correspond to them. If you feel an inner chakra, only then can you feel the corresponding spot; otherwise you can dissect the whole body, but nothing like chakras will be found.
All the talk and all the so-called evidence and all the scientific claims that your gross body has something like kundalini and chakras is nonsense, absolute nonsense. There are corresponding spots, but those spots can only be felt when you feel the real chakras. With the dissection of your gross body nothing can be found; there is nothing. So the question is not of anatomy.
