Yoga means union with God. The state of yoga is impossible to attain without the blessings of Lord Shiva. It needs a concentrated and focussed mind. There are some specific spots in the human body concentrating upon which, enables a man to attain the state of yoga-spot between the eyebrows, lower part of the throat, navel and six inches above it etc.
The state of yoga can never be attained until and unless a person has fully controlled the tendencies of sense organs. It can be achieved with the help of eight means- Yama (penance), Niyam (discipline), Asan (posture), Pranayama (breath-control), Pratyahar (restraint of passion), Dharan (retention), Dhyan (concentration) and Samadhi (deep meditation). Each of them holds an important position in the path of yoga.
Describing about the methods of performing yoga, Suta says— A person should sit with his legs crossed in Padmasan and try to concentrate his mind by fixing his gaze between his eyebrows. He should keep his spine erect. He should meditate either on the form of Omkar or on the form of lord Shiva. Breath control is an important aspect of yogic exercise. A man should exhale deeply for 32 times and then breathe in deeply. He should then retain his breath as long as possible and visualize lord Shiva within his body. By constant practice he will achieve mastery over this art and a time will come when he will experience divine bliss. This divine bliss can not be experienced unless one has attained a deep state of meditation (Samadhi).
