Ice remains ice until it reaches the critical temperature that melts it into water. Water remains liquid until it reaches the critical temperature that changes it into vapor. The same is true in practice. You may struggle for years to gain some psychic-mental ability and become discouraged because you are not making any progress. But you are moving toward the critical point without realizing it. One day, unexpectedly, you will awaken and begin to live consciously in the psychic-mental plane. <<The Magus of Strovolos>>
Many shifters, after much effort, become discouraged or give up, and then suddenly achieve success. This book explains the secret. It explains that changes are cumulative, even if they are not visible. In other words, if you keep going, you will eventually find success, even if it seems like there is no progress.
