"Sexual pleasure is a legitimate right of the human being." - Samael Aun Weor, The Three Mountains
You are doing it: by learning about consciousness and its relationship to the emotional center. Just observe what you experience in all three brains, but without being identified with any of them. The superior emotions appear slowly and gradually, like the arrival of Spring.
Until the ego is eliminated completely, lust is present, so be aware of it, and work on it. Along the way, the experience of superior emotions—and comprehension of how you reached their arrival (i.e. through chastity)—is a direct antidote to the power of lust to seduce us. When you genuinely comprehend chastity and what it brings with it, lust becomes powerless. Without this comprehension, lust remains very powerful.
