A perennial flow of Dharana (concentration) is called Dhyana or meditation. Meditation is a means of transforming the mind. Previously, Yogic meditation was the subject matter of philosophy. In the later half of the 20th century, it entered into psychology, physiology and medicine.   

Now it has a prestigious position in applied psychology, physiological science and clinical medicine.

Meditation involves achieving a state of 'thoughtless awareness' in which the excessive stress-producing activity of the mind is neutralized without reducing alertness and effectiveness. Research has scientifically proven that meditation is a safe and simple way to balance our physical, emotional, and mental state. Meditation is an approach that anyone can use to help cope with medical problems, stress and anxiety. Meditation has been found to bring about relaxation and balance cardiac, respiratory, hormonal and circulative systems. It is now recommended by many doctors for patients suffering from diverse psychosomatic and stress induced illness. Negative emotions like fear, anger, depression, tension, worry etc. are reduced and a calm state of mind with a positive personality is developed. Meditation helps to prolong the body's anabolic process of growth and repair and reduce the catabolic or decaying process.
