The human mind can transcend ordinary experience and exist at a higher level than normal, known as the superconscious state of concentration, concentration, and even transgress the limit of concentration. He comes face to face with facts that ordinary consciousness cannot comprehend. This is achieved by appropriate training and control of the subtle forces in order to give these, so to speak, an impetus to the mind into higher spheres. When the mind is thus elevated to the superconscious state of consciousness, it begins to operate from there and experiences the highest truths, acquires the highest knowledge. This is the highest goal of Yoga. For a Yogi, controlling vibrating Prana means kindling the flame of higher knowledge, self-knowledge. The highest goal is achieved through Pranayama.
