To hold wisdom requires the special condition that you learn and retain the learning, not just in your mind, but also where it can be accessed easily.
To explain this process more simply, if you can open your heart and mind during the learning process, the information is stored in the Chalice. Then, if you can then maintain the heart and mind in a state of repose, you can access the information at any time.
When I refer to learning, I do not mean learning in the normal sense of the word. I refer to the learning that comes from centuries of experience, centuries devoted to the inner knowledge of the adepts. Such learning includes, for example, knowledge about the true meaning of nature and how to work with the nature kingdoms, or knowledge about the true meaning of dharma and how dharma affects the evolution of the individual, or knowledge about the planet and how it has evolved.
When I say holding the wisdom, I mean more than remembering what you have learned. I mean taking the knowledge and applying it to your everyday life.
Holding wisdom changes your consciousness. There is no turning back and discarding wisdom, because it is an energy that affects every aspect of your spiritual growth.
To hold wisdom requires you learn & retain the learning, not just in your mind, but where it can be accessed easily.
