The mind and the body are both inert. Any energy or peace you experience can only come from the Self. Drop the identification with the body. These experiences are making you too body-conscious. Just be aware of the Self and try to pay as little attention as possible to the body. The Self is pure energy, pure power. Hold onto that.
The thoughts that come and go are not you. Whatever comes and goes is not you. Your reality is peace. If you don't forget that, that will be enough.
Your ultimate need is to get established in the changeless peace of the Self. For this you have to give up all thoughts.
Tayumanuvar, a Tamil saint whom Bhagavan often quoted, wrote in one of his poems: 'My Guru merely told me that I am consciousness. Having heard this, I held onto consciousness. What he told me was just one sentence, but I cannot describe the bliss I attained from holding onto that one simple sentence. Through that one sentence I attained a peace and a happiness that can never be explained in words.'
