Buddhist-Meditation-Systematic-and-Practical

If one practices the Pure Land meditations, take
advantage of dreams and try to go there. When one
wakes up a little, concentrate the mind and endeavor to
discover the Dharmakaya light again. Pray for this and
the Pure Land should also then appear.
Males should be careful of periods in the night when
one is in a half-awake state and one's organ becomes
erect, lustful thoughts thus invading the mind, leading
quickly to seminal discharge. As soon as one becomes
aware of either of these events, visualize the organ as a
vajra, the head of which turns inside itself and rises up
within the body. In this process, the semen about to be
discharged meets the "fire" and is melted or dispensed.
In this way one retains the semen and stops the lustful
thoughts.
36. Sleeping
If one is middle-aged or old it is usually neither
advisable nor necessary to sleep for a long time. If the
yogi cannot sleep properly and only turns over and over,
he should alert himself: "I cannot sleep, so why do I not
get up and practice meditation?" At midnight and in the
early morning, all is very quiet and it is a fine time to
practice.
Young people need enough sleep or they will only
experience a sleepy mind during the day, but they
should not on this account prolong their sleeping hours
unduly.
