The Mother’s help is always there but you are not conscious of it except when the psychic is active and the consciousness not clouded. The coming of suggestions is not a proof that the help is not there. Suggestions come to all, even to the greatest sadhaks or to the Avatars—as they came to Buddha or Christ. Obstacles are there—they are part of Nature and they have to be overcome. What has to be attained is not to accept the suggestions, not to admit them as the truth or as one’s own thoughts, to see them for what they are and keep oneself separate. Obstacles have to be looked at as something wrong in the machinery of human nature which has to be changed—they should not be regarded as sins or wrong-doings which make one despair of oneself and of the sadhana.
