John chapter 14 verse 1

John 14:1 points clearly to the following facts-

1. The decision-making whether truthful or false occurs in the heart. Why? Our soul the atman within the heart always prompts us on the right path. It is the ego driven self of a human being that prompts one on the worldly path... the path of wanton desires and materialistic riches!

"Let not your heart be troubled" clearly indicates that one must learn to believe in the existence of our soul the atman within. Our soul atman that resides within our heart! And this soul atman being a minuscule part of God never guides us on the wrong path.

If we are truthful to self... there is no cause to distrust the voice from within... the voice of our soul the atman within residing within our heart. John 14:1simply implies that we must learn to go by the dictates coming from within our heart... the dictates of our soul the atman within.
