Perceiving your own voice means perceiving your true self or nature. When you and the sound become one, you don't hear the sound; you are the sound.

To know what that true self is without social pressure is to know your true nature.

American dog say, 'Woof, woof.' Korean dog say, 'Mung, mung.' Polish dog say, 'How, how.' So which dog barking is correct? That is human beings' barking, not 'dog' barking. If dog and you become one hundred percent one, then you know sound of barking. This is Zen teaching. Boom! Become one.

Be your true self. Because if you're not, there are consequences to be paid.

This above all; to thine own self be true.

Genetics do play a role in how you consciously or subconsciously manifest your true self.
