The Sanskrit word 'Yoga' has two meaning, because it is derived from two roots - one is 'yujir yoge' and other is 'yuj samadhou'. The root 'yujir yoge' means to join or to unite. Religious leaders accept this meaning because their philosophy is based on dualism. They always try to project an external God and become Gog's representitives. By this they rule over their followers.
However the other root 'yuj samadhou' means to concentrate. Patanjali tried to preach that Yoga where mind is concentrated in order to realise the true self(svarup). Mind is concentrated when thoughts arising in mind is controlled through yogic practice. Total concentration(samadhi) is that state where mind is free from all worldly thoughts and a seer rests in his true self.
Patanjali's Yoga is called 'Ashtanga Yoga' for it is divided into eight parts or limbs. These are - Yama(abstention), Niyama(discipline), Asana(posture), Pranayama(breath control), Pratyahar(withdrawal), Dharana(to hold), Dhyana(meditation) and Samadhi(concentration)(II.29). Yama and Niyama are the external limbs which are to be observed in social life, while others are the internal limbs which are to be practiced in order to concentrate mind.
YAMA(abstention)
There are five kinds of Yama; these are - Ahimsa(nonviolence), Satya(truth), Asteya(not to steal), Brahmancharya(to think about Brahman) and Aparigraha(not to accept)(II.30).
Ahimsa - A Yogi should give up violence and cruelty against men and animals. When one gives up violence completely in thought as well as in action and remains firm in nonviolence, animosity disappears(II.35). Then one realises the unity of all.
Satya - While leading social life, one should be truthful. He who follows truthfulness none of his actions goes in vain(II.36).
Asteya - We should not steal or plunder other's wealth. Then we learn how to lead a modest life within our income or we learn how to increase our income. For this by remaining firm on Asteya, a Yogi receives all kinds of wealth(II.37).
Brahmancharya - A Yogi who has given up violence, is truthful always and depends upon his own wealth feels greatness. He thinks about his true self or soul(atman) and its great potential. The Upanishads describe this Atman as Brahman, the ultimate reality and truth. The task of a Yogi is to bear this highest knowledge in mind and proceed further in the practice of Yoga. By bearing knowledge of Brahman firmly one achieves vigour(II.38). This vigour makes his body and mind powerful. Brahmanchrya is not abstention from sex as believed by most people. The great saints of ancient India were married and at the same time practiced Yoga and realised the ultimate truth.
Aparigraha - Aparigraha is not to accept donations, alms or bribe. When one observes Aparigraha one comes to know how to lead life in this birth(II.39). When one does not depend upon others for a livelihood, one learns how to work and earn. Those who depend upon the earnings of others fail to realise their own potential or the potential of true self.
NIYAMA(discipline)
Niyama includes - Shaucha(ablution), Shantosh(contentment), Tapa(to heat), Svadhyay(self-study) and Ishvara Pranidhan(to bear God)(II.32).
Shaucha - It is to keep the body clean. By practicing Shaucha, body is protected and is made free from foreign matter(II.40). We should take bath regularly so that foreign matter sticking to the body are washed away. Also we should keep our environment clean so that practice of Yoga becomes fruitful.
Santosh - It is to remain content and happy. A content man achieves best happiness(II.42).
Tapa - The meaning of Tapa is to heat or to rule. By practicing Tapa, impurities in the body are destroyed and the body and senses are brought under control(II.43). Yogic exercises help remove impurities deposited in various parts of the body. While Shaucha is external purification, Tapa is internal purification. Heat generated during yogic exercise causes sweating and impurities are removed through sweating. By this body becomes fresh, active, powerful, beautiful and diseasefree. One rules over such a body and its senses and proceeds further in realising true self.
Different Yoga Masters teach different yogic exercises(yogasana). My late Master Munishvar Shiv kumar Shastri has developed an unique exercise called Chakrabhedan(circle interception) which is very useful for keeping body and mind under control. This may be practised by people of all ages.
Svadhyay - It is the reading of the self. One is nothing but a mind. So one should read his mind carefully. Through self-study one may understand one's own self. So how one may meet one's beloved God through self-study. This is because God is not different from one's true self.
Ishvara Pranidhan - In order to meet one's beloved God one should make oneself worthy of it. One should bear God or Godliness qualities in oneself. This is Ishvara Pranidhan. Through Ishvara Pranidhan one achieves Samadhi(II.45). Samadhi is the state of total concentration of mind on true self. Through Ishvara Pranidhan one achieves Samadhi, means one attains total concentration of mind on true self and meets one's beloved God.
Other limbs of Yoga shall be described in the next article.
