First of all, you must begin to seek Him, and then that must be the most important thing in life. The will must be constant, the aspiration constant, the preoccupation constant, and it must be the only thing you truly want. Then you will find Him.
But of course, if in one’s life one thinks of Him for five minutes and is busy with other things for three-quarters of an hour, there is not much chance of success. Anyway, it will take many lifetimes.
It must not be a pastime. It must be the exclusive preoccupation of one’s being, the very reason of one’s existence.
