According to Osho, choosing to focus on the positive does not deny total reality; it prepares you for it. From negativity you cannot leap into choiceless awareness, but positivity breeds courage, openness, and adventure. First move from misery to joy; then, from that spacious joy, you can drop both positivity and negativity and enter the choiceless, the beyond.
Look for the good first so you feel strong enough to drop all preferences and see everything just as it is.
