Obstacles – lack of receptivity

These obstacles are usual in the first stages of the sadhana. They are due to the nature being not yet sufficiently receptive. You should find out where the obstacle is, in the mind or the vital, and try to widen the consciousness there, call in more purity and peace and in that purity and peace offer that part of your being sincerely and wholly to the Divine Power.
