There is no doubt that many of those who attempt meditation at first find nothing for their labours, and even though at times they seem to be on the verge of finding something, it does not get realized. When after a sufficiently long period the seeming lack of success turns the effort into a bore, two things are indicated. A point has been reached where a greater patience is needed and the man must learn to go on waiting. Short periods without practice are then permissible if the strain is too much. The other indication is that the Short Path must be brought in or may even replace the work of meditation for the time being. But all this is subject to the qualification that the meditation is correctly conducted--so the method must be checked, the process must be understood and its purpose clarified.
