This new deluxe printing of these timeless teachings is a treasure to be read and referred to again and again by seekers treading the spiritual path. The classic Sutras (thought-threads), at least 4,000 years old, cover the yogic teachings on ethics, meditation, and physical postures, and provide directions for dealing with situations in daily life. The Sutras are presented here in the purest form, with the original Sanskrit and with translation, transliteration, and commentary by Sri Swami Satchidananda, one of the most respected and revered contemporary Yoga masters. In this classic context, Sri Swamiji offers practical advice based on his own experience for mastering the mind and achieving physical, mental and emotional harmony.
