YOGA SHIK UPANISHAD

It means, the union between 'Apana and Prana, Ida Nadi with Pingal Nadi, solar energy with the moon, and 'individual soul with the universal soul' is called yoga.

Every living being has a soul that works as a vital force for the entire body and mind. The body and mind do not work on their own because they are unconscious.

But the soul is conscious and the body and mind appear to be conscious because of the presence of the conscious, soul. The body is made of five elements viz. Space, air, fire, water, and earth. The union of the individual's soul with these five elements is called birth and disconnection is called death.
