Many people think that being spiritual means being positive, but being spiritual means being conscious and aware. To become conscious is a much different thing than to become positive. To become conscious and aware, we must become authentic. Authenticity includes both positive and negative.
Spirituality lies not in the power to heal others, to perform miracles, or to astound the world with our wisdom, but in the ability to endure with right attitude whatever crosses we have to face in our daily lives, and thus to rise above them.
