There is the true psychic which is always good and there is the psychic opening to mental, vital and other worlds which contain all kinds of things good, bad and indifferent, true, false and half true, thought-suggestions which are of all kinds, and messages also which are of all kinds. What is needed is not to give yourself impartially to all of them but to develop both a sufficient knowledge and experience and a sufficient discrimination to be able to keep your balance and eliminate falsehood, half-truths and mixtures. It will not do to dismiss impatiently the necessity for discrimination on the ground that that is mere intellectualism. The discrimination need not be intellectual, although that also is a thing not to be despised. But it may be psychic discrimination or one that comes from the higher supra-intellectual mind and from the higher being. If you have not this, then you have need of constant protection and guidance from those who have it, and who have also long psychic experience, and it may be disastrous for you to rely entirely on yourself and to reject such guidance.
In the meantime there are three rules of the sadhana which are very necessary in an earlier stage which you should remember. First, open yourself to experience but do not take the bhoga of the experiences. Do not attach yourself to any particular kind of experience. Do not take all ideas and suggestions as true and do not take any knowledge, voice or thought-message as absolutely final and definitive. Truth itself is only true when complete and it changes its meaning as one rises and sees it from a higher level.
The middle path is made for thinking man.
To choose his steps by reason's vigilant light,
To choose his path among many paths
Is given him, for each his difficult goal
Hewn out of infinite possibility.
