In the views of Patanjali, who is supposed to be the founder of yoga, the meaning of the word 'yuj' is to stabilise the mind for the union of Atma and Parmamtma. In short we can say that yoga is a way to join god. In modern times yoga play a very important role in our life. Each individual run after money.

Therefore Each individual must regular practices of yoga to make a happy life. yoga is very helpful to remove the tensions, make concentration, free from sufferings and improve the physical health. Moreover, it develops optimum level of health to lead happy an prosperous life (Ward et al., 2014). Yoga aims through its practices to liberate a human being from the conflicts of duality (body-mind), which exists in every living thing, and from the influences of gunas, the qualities of universal energy that are present in everything. In other words, one of the yoga practices, hatha yoga is based on the knowledge, development, and balance of psychophysical yoga. The three main elements used in hatha yoga to attain its purposes are the body, physical part of the man; the mind, the subtle part; and the element that relates the body with the mind in a special way, the breath (James and Raub., 2002). On the other hand, Yoga consists of eight stages (Yama, niyama, asan, pranayama, pratyahara, dharana, dhyana, samadhi) to achieve the union of Atma and Parmatma. It is basic principles for the benefit of society such as honesty, truthful, non-violence, non-steal and absence of lust (Giri, 2006) Niyam It is the basic principles for self like a healthy body, hygienic habits, proper diet, sleep, rest, work routine, etc. (Babu, 2012) Asanas It is slow stretching activities performed to improve the whole body fitness (Giri, 2006) Pranayam It is a systematic control of breathing performed to improve the internal functioning of the whole body. (Malhotra et al., 2004) Pratyahara It develops the inner mental strength by controlling sense organs (Mallison, 2004) Dharana It helps to fixing the concentration on single object i.e., concentration (Giri, 2012) Dhyana It help to make a high level of concentration (James and Raub, 2002) Smadhi It is state of union with god (Giri, 2012) The various categories of yoga are discussed in table 1. "Yoga is a union of atma and parmatma" Satyapal "Yoga is derived from sanskrit word 'yuj' which means the union of soul with god" Shankracharya "Yoga is withdrawal of senses organs from the worldly objects and their control".

There are numerous ways of Pranayams based on this technique of inhale, exhale, and holding of breathing include kapalbhati, bhastrika, nauli, jalaneti and sutar neti (Malhotra et al. , 2009).

A) Kapalbhati pranayama
Kapalbhati pranayama is an important kind of breathing exercise that helps to relieve of various ailments over a period of time. The word kapalbhati is composed of two words kapal and bhati.

In the words of Gherand samhita, Kapalbhati is deliberated mainly to the cleaning of other effects. The process of kapalbhati include short and strong forceful exhalations and inhalation happen automatically. Kapalbhati include vatakrama, vyutkrama, and sheetkrama kapalbhati.
1) Vatakrama kapalbhati:-It is similar to bhastrika, a mechanism of pranayama, expect that exhalation is active while inhalation is passive, the opposite of normal breathing.
2) Vyutkrama kapalbhati:-It is similar to jala neti, it includes sniffing water through the nostrils and letting it flow down into the mouth and then spitting it out.
3) Sheetkrama kapalbhati:-It is reversed of vyutkrama kapalbhati, in which water is taken through the mouth and then expelled through the nose.
In addition to patient's suffereing from heart trouble, lung trouble should practice this under an expert guidance. Each individual who are suffering from diseases of blood circulation should also perform the process under guidance and care of experts.

B) Bhastrika pranayam
The term bhastrika pranayam can be considered as increases the flow of air into the body to produce inner heat at the physical and subtle level. It is also known as bellows breathe. It is helpful to release toxins present in the body that are produced from excess of air, bile, and phlegm, relief in various throat inflammations, remove diseases of the nose and chest and eradicates ashtma etc., expand and fortifies our nervous system, burn fat and promote naturally weight loss. In addition to this pranayam is strictly prohibited for those who are suffering from heart problems and high blood pressure (Bhavanani et al., 2012).

C) Jala neti
The term jala neti literally means "water cleansing". Jala neti is performed as routinely as using a toothbrush. Jala neti is performed daily usually the first thing in the morning with other cleansing practices. Sometimes it is done more often such as the end of the day if you work or live in a dusty or polluted environment. When dealing with problem of congestion it can be peformed up to four times a day and has been shown up to speed the healing process for common colds (Shankarappa, 2012). In jala neti, the warm salty water flow through one side of the nasal cavity and out the other nostril. It is helpful to remove all dirt and bacteria filled mucus from within the nose. Jala neti is also helpful for headaches, epilepsy, depression and general mental tension. Neti is of great importance for problems related with the eyes. Neti is admirable for those who are trying to quit smoking (Bhavanani et al., 2012).

D) Nauli
Nauli can be considered as a yogic cleansing exercise or kriya. Nauli cleanses the internal organs and abdominal region such as side-to-side rolling motion of the abdominal muscles (Panwar et al., 2012). In other words we can say that this massage is great for your kidneys and liver, your bladder and your pancreas, gall bladder and reproductive organs. Nauli is also beneficial for those people who are suffering from diabetes. In the views of Brian Dana Akers "lower the shoulders. Revolve the stomach left and right with the speed of a strong whirlpool. This is called nauli by the masters. this nauli is the crown of hatha practices. Nauli encourages a weak gastric fire, restore the digestion, always bring happiness, and dries up all defects and diseases" (Malthotra et al., 2009). Nauli is also considered as an difficult exercise, which can be learned only perseverance and patience. Nauli is helpful for the recovery of constipation. The exercise may clean the small intestine and eliminate digesting problems. In addidition to nauli should not be performed by pregnant women or people with hypertension, heart diseases, or various gastrointestinal ailments. Figure 1 shows that with the help of yoga, body can be purified through pranayama such as kapalbhati, bhastrika pranayam, jala neti, and nauli as discussed earlier.
