Yogi Swatmarama 15th and 16th C
Swami Swatmarama was the follower of Natha Tradition, (followers of Adi Nath or Lord Shiva), taught by great Gurus like Gorakshanath and then Matsyendranath. This is the tradition of sages who live in caves or Himalayas and renounce material life adopting sanyasa.
The meaning of word Hatha, it is made up of Ha + Tha. “Ha” means Pingala Nadi (sun principle) or right nostril and “tha” means Ida nadi, (moon principle) or left nostril.
Nadi means psychic passage of energy which can be compared with nerves in physical body.
Hatha means balance of Ida and Pingala Nadis, or balancing of mental energy of Ida and Vital / physical energy of Pingala Nadi. Ida Nadi can be compared with Parasympathetic Nervous system and Pingala nadi can be compared with Sympathetic Nervous System.
Hatha Yoga practices results in balancing the entire nervous system resulting in balance of Body and Mind, physical energy and mental energy.
Hatha Yoga Pradipika starts with the Shatkarmas or cleansing processes, these processes are to remove the blockages in Nadis (psychic / pranic energy channels). The purification is the first in Hatha Yoga, once the body is free of disease, the next step is recommended and that is asanas.
Hatha Yoga Pradipika outlines the purpose of asana, which says that “One can achieve Sound Health, Stability, Lightness of Body and Mind with Asana”. Asana result in disciplining the Body and Mind.
Before the asanas comes Pranayama, it is made up of Prana + Ayama, which means the control and extension of the Prana or vital energy or bio energy. Pranayama, if practiced correctly can cure all types of physical and mental disorders, also increase in pranic energy can increase functioning of brain and may result in Siddhis or perfections or extra sensory perceptions, Pranayama is used to control the mental energy and mind. But if pranayama is not done properly, it invites all the diseases. So it must be done under the guidance of Guru.
Pranayama is considered as a fast way to awaken the kundalini. But if one is not prepared to take on this high level energy awakening then this may have negative effects on mind and body. So Pranayama is always practiced under the guidance of a teacher.
Bhandas are necessary for practice of Pranayama, Bandha means energy lock. There are main 3 types of locks, first is Jalandhar Bandha or Chin lock, second is Moolabandha or anus lock and third is Uddiyan Bandha or abdominal lock. These locks are essential while doing the Kumbhaka that is retaining the air inside or outside of the lungs. If Kumbhaka or retention is done without Bandhas, it may have a very negative effect.on digestive system, excreatory system, nervous system, brain etc…
Hatha Yoga also describes Mudras or gestures or Mental attitude, which induce the state of Pratyahar (Sense withdrawal) and results in spontaneous state of meditation. Several mudras are mentioned in the Hatha Yoga.
