To know yourself as the Being underneath the thinker, the stillness underneath the mental noise, the love and joy underneath the pain, is freedom, salvation, enlightenment.
When the dog looks at you, the dog is not thinking what kind of a person you are. The dog is not judging you.
If small things have the power to disturb you, then who you think you are is exactly that: small.
Jesus said, 'The Kingdom of Heaven is within you.' I think if he lived nowadays, instead of 'kingdom,' he would have said, 'dimension.' And 'heaven' refers to a sense of vastness or spaciousness.
In the egoic state, your sense of self, your identity, is derived from your thinking mind - in other words, what your mind tells you about yourself: the storyline of you, the memories, the expectations, all the thoughts that go through your head continuously and the emotions that reflect those thoughts. All those things make up your sense of self.
When people get taken over by the ego to such an extent, there is nothing else in their mind except the ego. They can no longer feel or sense their humanity - what they share with other human beings, or even with other life forms on the planet. They are so identified with concepts in their minds that other human beings become concepts as well.
