Habit patterns, practice and sleep
The human personality is composed of habit patterns. If yoga nidra is practiced regularly like the practice of meditation, habit will lead you spontaneously to this state. Otherwise to remain fighting mentally—because you are only practicing occasionally—brings frustration.
When you think that it is difficult to practice, then it really becomes difficult. But when you decide and determine to practice, your willpower and determination will lead you to achieve what you want to do.
Yogis reduce the amount of sleep to two and a half hours, and finally to no sleep. Using “sleepless sleep,” they go to a state of deep meditation instead of sleep. When meditation becomes your whole life this change naturally occurs.
