“Q: Are so-called prophetic dreams a sign that the dreamer has strong clairvoyant faculties?
A: It may be said, in the case of persons who have truly prophetic dreams, that it is because their physical brains and memory are in closer relation and sympathy with their “Higher Ego” than in the generality of men.
The Ego-Self has more facilities for impressing upon the physical shell and memory that which is of importance to such persons than it has in the case of other less gifted persons.
*Remember that the only God man comes in contact with is his own God, called Spirit, Soul and Mind, or Consciousness, and these three are one.*
But there are weeds that must be destroyed in order that a plant may grow.
We must die, said St. Paul, that we may live again. It is through destruction that we may improve, and the three powers, the preserving, the creating and the destroying, are only so many aspects of the divine spark within man.
Q: Do adepts dream?
A: No advanced Adept dreams. An adept is one who has obtained mastery over his four lower principles, including his body, and does not, therefore, let flesh have its own way. He simply paralyzes his lower Self during Sleep, and becomes perfectly free.
A dream, as we understand it, is an illusion. Shall an adept, then, dream when he has rid himself of every other illusion? In his sleep he simply lives on another and more real plane.”
Q: Are there people who have never dreamed?
A: There is no such man in the world so far as I am aware. All dream more or less; only with most, dreams vanish suddenly upon waking. This depends on the more or less receptive condition of the brain ganglia.
Unspiritual men, and those who do not exercise their imaginative faculties, or those whom manual labour has exhausted, so that the ganglia do not act even mechanically during rest, dream rarely, if ever, with any coherence.”
