You will better gauge the quality of your transmutation based upon the purity of your mind.
It is necessary to discriminate between consciousness and lust. If your mind is cloudy and you do not comprehend what you are doing, then you need to develop meditative serenity and comprehension.
Comprehension unfolds as we strengthen our ability to focus without distraction, but also to do so with a vivid, intensified, clarified perception. This is why we practice meditation, balancing concentration and visualization exercises to enhance our conscious capacities.
As for Gnostic groups, we have a Distance Learning Program you can sign up for.
