Does Not Give Instructions in Yoga to Outsiders [4]
I am instructed by Sri Aurobindo to reply that he does not give advice or instructions to anybody except his own disciples (already accepted by him), those whom he finds fitted and ready 
to prepare themselves for his path. This path has neither the same aim nor the same method as the ordinary Yoga, it aims at a realisation of which their results are only component parts; it may be said to begin its capital experiences where these end and its object is one that they would consider impossible. Much of it is virgin ground in which the paths have yet to be cut and built. The obstacles and difficulties in the way of success are formidable and demand either a strength and patience or a faith and unquestioning reliance on the Guru who is the pathfinder and leader. Or otherwise they have to have so strong and clear a call that no difficulties matter, or else to be in some way predestined to follow this path and no other, to cleave to Sri Aurobindo and the Mother as Guru and to no other. Your preparation seems to be mainly intellectual and for this Yoga the intellect is not sufficient; relied upon as the chief guide it may become instead a barrier. This Yoga depends upon a supra-intellectual knowledge which can come only from the soul or psychic being within and the secret spirit above. Moreover attachment to ideas, people, things are hampering obstacles in this Yoga. You could perhaps understand for yourself that there may be many obstacles in the way of your accepting this Yoga. All the same, if you still wish and are able to come for Darshan next August, you may do so. But for the moment for the reasons pointed out Sri Aurobindo is not able at present to give you any instruction or suggest a discipline.
