If the candidate is found fit for the foregoing experiences, he is then given what is called symbolically the draught of forgetfulness. This means that he is initiated into the secret knowledge that enables him to act without being continually disturbed by the lower memory. This is necessary for the initiate, for he must have full faith in the immediate present. He must be able to destroy the veil of memory which envelops man every moment of his life. If we judge something that happens to us today according to the experience of yesterday, we are exposed to a multitude of errors.
Of course this does not mean that experience gained in life should be renounced. It should always be kept in mind as clearly as possible. But the initiate must have the ability to judge every new experience wholly according to what is inherent in it, and let it react upon him, unobscurred by the past. We must be prepared at every moment that every object and every being can bring to us some new revelation. If we judge the new by the standard of the old we are liable to error.
The memory of past experiences will be of greatest use for the very reason that it enables us to perceive the new. Had we not gone through a definite experience we should perhaps be blind to the qualities of the object or being that comes before us. Thus experience should serve the purpose of perceiving the new and not of judging it by the standard of the old. In this respect the initiate acquires certain definite qualities, and thereby many things are revealed to him which remain concealed from the uninitiated.
The second draught presented to the initiate is the draught of remembrance. Through its agency he acquires the faculty of retaining the knowledge of the higher truths ever present in his soul. Ordinary memory would be unequal to this task. We must unite ourselves and become as one with the higher truths.
