Stages of YOGA. Must see post for everyone.

The word yoga is derived from the Sanskrit root yuj meaning to bind the yoke. It is the true union of our will with the will of God.
Our ancient sages have suggested eight stages of Yoga to secure purity of body, mind and soul and final communion with God.
These eight stages are known as Ashtangayoga.The eight stages of Yoga are as follows :

Yama (Social Discipline): Yama means restraint or abstention. It contains five moral practices. They are: Non-violence (Ahimsa), Truthfulness (Satya), Non-stealing (Asteya), Celibacy (Brahmacharya) and Non-acquisitiveness (Aparigraha).

Niyama (Individual Discipline): Rules of conduct towards oneself consist of certain disciplines which are both physical and mental. These are five in number:Cleanliness (Shaucha), Contentment (Santosha), Austerity (Tapas), Self-Study (Svadhyaya) and Surrender to God (Ishvara Pranidhana)

Asana (Postures): Asana means holding the body in a particular posture to bring stability to the body and poise to the mind. The practice of asana brings purity in tubular channels, firmness to the body and vitality to the body and the mind. There are many asanas, but keeping in view a comman's health, 65 asanas have been in practice and will be soon available at this website.

Pranayama (Breath Control): The literal meaning of Pranayama is Breath Control. The aim of practising Pranayama is to stimulate, regulate and harmonize vital energy of the body. Just as a bath is required for purifying the body, so also Pranayama is required for purifying the body. Just as a bath is required to purifying the body, so also Pranayama is required for purifying the mind.

Pratyahara (Discipline of the Senses): The extroversion of the sense organs due to their hankering after worldly objects has to be restrained and directed inwards towards the source of all existence. This process of drawing the sense inwards is Pratyahara or putting the sense under restraint.

Dharana (Concentration): Dharana means focusing the pure mind on one's personal deity or on the individual self. The practice of Dharana helps the mind to concentrate on a particular object.

Dhyana (Meditation): When one sustains and maintains the focus of attention through Dharana unbound by time and space, it becomes Dhyana (Meditation). Deep concentration destroys the Rajas and Tamas Gunas of mind and develops the Satvika Gunas (qualities).

Samadhi (Self-Realisation): The eight and final stage of Yoga is Samadhi. At this stage, one's identity becomes both externally and internally immersed in meditation. The meditator, the act of meditation and the object meditated upon, all the three shed their individual characteristics and merge with one single vision of the entire cosmos. Supreme happiness, fee from pleasure, pain or misery, is experienced. Samadhi is the climax of Dhyana.
