The sudden but gentle drawing away from outer activity to the inner one, "the melting away in the heart," as Oriental mystics call it, felt actually inside the middle-chest region, may make itself felt occasionally, or, in an advanced or regular meditator, every day. In the last case it will tend to appear at around the same hour each time. This is a call which ought to be treated properly with all the reverence it deserves. But before it can be honoured it must be recognized. Its marks of identification must be studied in books, learned from experience, gleaned from the statements of other persons, or obtained from a personal teacher. When it comes, the man should heed the signal, drop whatever he is doing, and obey the unuttered command to turn inwards, to practise remembrance, or to enter meditation.
