We not only 'see', but while we 'see', two other actions take place side by side: catharsis and nourishment. The first action is to 'see'. We 'see' the toe and then comes the suggestion that the element which is alien to the toe is getting purged. After some time comes the suggestion that the pure blood is flowing and nourishing the toe. Thus, it is a three-dimensional process, which involves 'seeing' purging, and nourishing the toe. We can solve quite a few of our problems by 'seeing' every organ of our body through this process.
'Seeing' is very difficult. It is difficult because there is no sustained concentration of the mind. We perceive our breath, our body and our psychic centers. Even while engaged in the act of 'seeing', we have to learn first to concentrate. With growing concentration of the mind, we would be able to see correctly the definite point. If concentration of the mind is not achieved, there would be such a web of alternatives that we would forget about 'seeing' and get entangled in those alternatives instead. This is what happens when the art of the seeing has not been mastered.
There is one experiment of looking at the tip of one's nose. Once you start, you go on looking at it, concentrating your attention on it. Anyone who has done this experiment must have definitely experienced that while concentrating on the tip of the nose, the attention goes to moola-nadi and as a result, the moola-bandha automatically comes about. That is the connection between them. When one begins 'seeing' one particular organ, all the related organs get activated. It is the art of 'seeing' that needs to be learnt.
