The big mind in which we must have confidence is not something which you can experience objectively. It is something which is always with you, always on your side. Your eyes are on your side, for you cannot see your eyes, and your eyes cannot see themselves.
Eyes only see things outside, objective things.
If you reflect on yourself, that self is not your true self any more. You cannot project yourself as some objective thing to think about. The mind which is always on your side is not just your mind, it is universal mind, always the same, not different from another's mind.
