What is yog?

Yoga means the end of pursuing the means of physical welfare or pleasure (which are termed as the reason behind suffering) and creating a permanent connection (yog) with God.

That is the natural thing, the pursuing of physical pleasure by human beings is not the real human self (its called maya), the real human self is being stable in God.

So snapping off the connection with maya and connecting permanently with God is called Yog.

This permanent connection if achieved through work/service then it is named as Karmayog.

If it is achieved through knowledge then it is gyanyog.

If it is achieved through love for God then it is bhaktiyog.

If it is achieved through harmonisation of world then it is called layayog.

If it is achieved through pranayam then it is hathayog and

If it is done through self control etc then it is called ashtangayog.
