parbawatiya: Happiness is a state of mind, therefore the real source of happiness lies in the mind, not in external circumstances. If our mind is pure and peaceful we shall be happy, regardless of our external conditions, but if it is impure and unpeaceful we shall never find happiness, no matter how much we try to change our external circumstances.
One way to get free of attachment is to cultivate the witness consciousness, to become a neutral observer of your own life. The witness place inside you is simple awareness, the part of you that is aware of everything — just noticing, watching, not judging, just being present, being here now. ~Ram Dass
