This is because the body, mind, and mouth are not yet controlled and in harmony. Therefore on some nights, the meditation is comfortable and ascends, but on others it descends and is in darkness. Because it is so, the practitioner feels bored and lazy and grows weary. The meditation practitioner must be a person of tenacity, courage, decisiveness, and persistent will. He or she must be a great person who considers secular life inadequate. The practitioner is not different from a rower who weighs anchor and is determined to reach the other side—the enlightened shore. Because the mind and will of the meditation practitioner are like that, if there is a boring night, it must be a night of effort to chase away the phantoms of laziness and tardiness.
