Wake up naturally (Dreaming, 41)

Crossing the second gate is a very serious affair, it requires the most disciplined effort. (Dreaming, 43)

Change dreams in an orderly and precise manner. (Dreaming, 44)

Cross by dreaming another dream and wake up from the second dream or use items of a dream to trigger another dream. (Dreaming, 44)

The second gate of dreaming is reached and crossed only when a dreamer learns to isolate and follow the foreign energy scouts. (Dreaming, 107)
