The chief obstacle in you is the mind. If you can quiet your mind and give the psychic being a chance, that will be your spiritual salvation. Your mind is inordinately active, too full of questionings, too shrewd, worldly and practical, too much given to doubt and self-defence.
All that is very useful in worldly life, it helps to bring success, but it is not the way to succeed in Yoga. No doubt in Yoga, the critical rational mind (self-critical as well as critical of things outside you) is an element that has its value so long as the true inner discrimination does not come; but of itself it cannot carry you on the way, it will only make your progress slow and stumbling. There must be something in
you that will open itself directly to the Truth and Light.
