The concepts and practices of Yoga originated in India about several thousand years ago. Its founders were great Saints and Sages. The great Yogis presented rational interpretation of their experiences of Yoga and brought about a practical and scientifically sound method within every one’s reach. Yoga today, is no longer restricted to hermits, saints, and sages; it has entered into our everyday lives and has aroused a worldwide awakening and acceptance in the last few decades. The science of Yoga and its techniques have now been reoriented to suit modern sociological needs and lifestyles. Experts of various branches of medicine including modern medical sciences are realizing the role of these techniques in the prevention and mitigation of diseases and promotion of health.

Yoga is one of the six systems of Vedic philosophy. Maharishi Patanjali, rightly called "The Father of Yoga" compiled and refined various aspects of Yoga systematically in his "Yoga Sutras" (aphorisms). He advocated the eight folds path of Yoga, popularly known as "Ashtanga Yoga" for all-round development of human beings. They are:- Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana and Samadhi. These components advocate certain restraints and observances, physical discipline, breath regulations, restraining the sense organs, contemplation, meditation and samadhi. These steps are believed to have a potential for improvement of physical health by enhancing circulation of oxygenated blood in the body, retraining the sense organs thereby inducing tranquility and serenity of mind. The practice of Yoga prevents psychosomatic disorders and improves an individual’s resistance and ability to endure stressful situations.

• Gyana Yoga: Teaches us to discriminate between self and non-self and to acquire the knowledge of one’s spiritual entity through the study of scriptures, company of Saints and practices of meditation.
• Bhakti Yoga: Bhakti Yoga, a system of intense devotion with emphasis on complete surrender to divine will. The true follower of Bhakti Yoga is free from egoism and remains humble and unaffected by the dualities of the world.
• Raja Yoga: Raja Yoga popularly known as “Ashtanga Yoga” is for all-round development of human beings. These are Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana and Samadhi.
• Swara yoga: Swara Yoga is the Science which is about the realization of cosmic consciousness, through the awareness/ observation then control/ manipulation of the flow of breath in the nostrils. Swara Yoga involves the systematic study of the breath flowing through the nostril (or Swara) in relation to the prevailing phases of the Sun, Moon, time of day and direction. It is the association of the breath in relation to the activities or phases or positions of the Sun, Moon, Planets, Seasons, Time of day, with the physical and mental conditions of the individual and then taking the appropriate action according to these subtle relations.
• Kundalini Yoga is a part of Tantric Tradition. Since the dawn of creation, the Tantrics and yogis have realised that in this physical body, there is a potential force residing in Muladhara Chakra, the first of seven Chakras. The seat of Kundalini is a small gland at the base of the spinal cord. In the masculine body it is in the perineum between the urinary and excretory organs. In the female body its location is at the root of the uterus in the cervix. Those people who have awakened this supernatural force have been called Rishis, Prophets, Yogis, Siddhas and other names according to the time, tradition and culture.
  To awaken the Kundalini, you must prepare yourself through yogic techniques such as Shatkriya, Asana, Pranayama, Bandha, Mudra and Meditation. Awakening of Kundalini results in an explosion in the brain as the dormant or sleeping areas start blossoming like flowers.
• Nadi: As described by Yogic texts, Nadis are flow of energy which we can visualize at the psychic level as having distinct channels, light, colour, sound and other characteristics. The entire network of nadis is so vast that even yogic texts differ in their calculations of the exact number. Reference in the Goraksha Shataka or Goraksh Samhita and Hatha Yoga Pradipika place their number at 72,000; emerged from the navel center- the Manipuri Chakra. Of all the thousands of nadis, Susumna is said to be the most important. The Shiva Swarodaya enumerates ten major nadis which connect to the ‘doorways’ leading in and out of the body. Of these ten, Ida, Pingala and Sushumna are the most important, they are the high voltage wires which conduct the energy to the substations or Chakras situated along the spinal column.
