The Arcane School exists for novices and after they have made some progress they get into a rut unless they leave it.
One can have great admiration for Krishnamurti personally; he is doing useful work in debunking the nonsense which largely vitiated the theosophic movement, of which the school is only a variant. He is doing good by removing the superstitions and the flabbiness of the average theosophist. However, this is not to say that one endorses all his ideas. He has a particular work of criticism to carry out and does it admirably, but he lacks a constructive technique. He goes to extremes. In his righteous rebellion against the hallucinations of clairvoyants, the exploitations of religion and occultism, the deliberate self-deception of teachers, and the enslavement of disciples, he wants to throw overboard much that is useful and necessary. Meditation generally ends in a desert waste, but under proper guidance it can become immensely fruitful in every way. The pity is that there has rarely been a rational approach to it. Many good things have become so hopelessly mixed up with silly nonsense and personal exploitation that sensible people react in time as Krishnamurti reacted. Krishnamurti has attained a high level of discernment but it is not realization in the ultimate sense. He often comes very close to the truth, but shoots off at a tangent again. Had he realized this he would have been better balanced and done greater good.
The work of the Arcane School is excellent in its place. It cannot be considered to be of real rather than illusory assistance to those who have got beyond an elementary stage. One can be much in accord with Krishnamurti in his criticism of occult organizations, so far as people of sufficient ability to think for themselves are concerned.
