Response:

What you have described is the classic experience of the feeling of separation between the body personality and the silent witness. 

In the early days of the awakening of the higher self, it is almost as if your inner seer is disinterestedly watching your body and mind go through its mundane daily activities. 

This apparent disconnection of feeling between your inner and outer worlds can sometimes be a little disorienting because you don’t feel as strongly about things as you used to. 

That is the heaviness you remarked upon.

This is a temporary phase, and once you have become adjusted to interacting to the world with self-referral awareness instead of the object-referral awareness, then you will regain your passion and the natural integration of experience. 

But instead of being attached to the objects of perception and the consequential confusion of who you are with respect to your experience, now the inner self is liberated and aware of its true nature regardless of what it is experiencing. 

As your development unfolds, it will become more joyful and light.

Love,

Deepak
