There are a number of traditional texts on Hatha yoga, but the most significant and influencial is the Hatha Yoga Pradpika by Svatmarama (approx 1350.) Other key texts include the Shiva Samhita and Gheranda Samhita.
Within Hatha yoga today there are lots of different schools, traditions and styles: such as Ashtanga, Sivananda, Vinyasa
Although these are all slightly different approaches that may incorporate techniques from other yoga paths, they are all essentially Hatha Yoga.'Ha' symbolises Sun and represents the physical body.
'Tha' symbolises Moon and represents the subtle mind.
Therefore, Hatha Yoga can be translated as:
'The Union of the Body with the Mind.'
When mind and body are in harmony we are able to experience a greater sense of peace, clarity and good health. From this platform we are able to work towards ultimate liberation. The goal of Hatha Yoga, as with all paths of yoga is self-realisation and freedom from suffering.
