What exactly is Subtle-Body Relaxation? How to Achieve It?

i learn from the Vedas that a complete human body has, over and above a soul, a bunch of other machinery as well...i am not talking about the Physical body...i'm talking about the Subtle-Body! Further i got to learn that, this subtle-body is composed of Mann (mind), Buddhi (Intel) and Chitt... show more i learn from the Vedas that a complete human body has, over and above a soul, a bunch of other machinery as well...i am not talking about the Physical body...i'm talking about the Subtle-Body!

Further i got to learn that, this subtle-body is composed of Mann (mind), Buddhi (Intel) and Chitt (Concentration/focus) and Ahamkar (ego)...

Now, the vital point that constitutes my question is...in to-day's kali-struck age, it's our subtle-body that is loaded more than our gross (physical) body...so, is there any way in the Vedic Scriptures, to refreshen and recharge this highly complex mechanism?
