When your mind is silent, such as when you are meditating or when you are just being in nature, your pure awareness, your essence, is not obstructed by the constant dialogue of the chattering mind. That is when you can fully experience your true nature—your true Self—your essence—your spirit—pure awareness. Your essence cannot be seen with the eyes. It is pure Being. You are pure being.
When you accept your Self 100%, living a peaceful and joyful life is possible. Non-acceptance of Self, even at the least bit, makes it impossible to live peacefully and joyfully. Anything that you continue to identify with from the past—you must let go of. If you have regrets over past decisions and choices that you made and action(s) that you took, you have to let them go. If you blame yourself for others decisions, choices, and actions, you have to stop blaming yourself. If you are holding onto resentment and bitterness towards others—you have to let it go. You cannot control other people. Accept that and you will be at peace.
