How we see others gives us an important insight about how we see ourselves. It is often that we project out into the world what we believe about ourselves. If we think of ourselves as good, we have hope in people. If we think that no matter what good deeds we do, we are still bad people, then we see others as fatally flawed.
In yogic teachings, we are told that we are Holy. The Upanishads teach the same idea again and again, while using different discourses or mahavakyas to teach it. So ham. Aham brahmasmi. Tat twam asi. It is a teaching we must be able to get if we are ever to reach the state of yoga. From ancient teachings passed on to us, we are told: I Am That (That which is immortal and everlasting). I Am Brahman (I Am One with the Absolute Reality). That Thou Art (Identification with the Absolute, 'That'). In this wholeness, in this reality, in this immortality, remember and believe in your goodness.
