Mind can be likened to water. Even to look at a stream of pure water running in all its purity is the greatest joy one can have, and drinking the pure water is so too. And so it is with the mind. Contact with the pure-minded is the greatest joy, whether they speak with one or not; there emanates from them a purity, a natural purity, which is not man-made but belongs to the soul and gives one the greatest pleasure and joy.
