Meditation on Siddhas as main goal of spiritual practice leads to activity of ego. Selfish wishes of getting supernatural abilities can block spiritual growth. As well as any selfish wishes. Actions from need, but not from desire, lead to quick spiritual development. Stopping of craving for Siddhas may lead to achievement of these Siddhas. Purifying of wishes leads to spiritual growth. Washing the wishes from Selfishness leads to erasing of negative consequences. Concentration on anything except Ego leads to opening of your Spiritual Eyes. Siddhas are being picked up with no attachments to them, we need no burdens.
