1. Record every dream you have, whether it is objective (cognizant) or subjective (hallucinatory and of the mind) since every dream indicates with precision the given state of our five cylinders (intellect, emotions, movement, instinct, and sex).
Study Dream Yoga, the collected writings of Samael Aun Weor on this subject. He explained that we must study all our dreams, since as Plato taught, "A man is known by his dreams."
2. Try pulling your finger to make it stretch. Or try placing your hand through a glass window (gently, of course!). If you're in the astral and if you're concentrated, your fingers will go through the window, since matter is protoplasmic in the astral plane.
Joyful in hope, suffering in tribulation, be thou constant in thy prayer.
Benedictis, qui venit in nomine Domini. Osanna in excelsis.
"Blessed is he who comes in the name of the Lord. Hosanna in the highest!"
