Sit in any meditative pose, with back erect and place the hands on the knees in gyana mudra. Look forward at a fixed point. Then look upwards as high as possible, without moving the head. Concentrate and focus the eyes on the eyebrow centre and meditate on the self (atma) or on the supreme consciousness. Here fix the vision in between the eyebrows.
By this practice one can control the mind, intellect and ego, and can enter the spiritual realms of consciousness. It is a powerful technique for awakening ajna charka. Physically, it strengthens the muscles of the eyes. Mentally, it calms the mind, removing stress and anger and develops the power of concentration. It improves the nervous system by releasing tension, and also helps in insomnia.
