If you find yourself craving a spiritual high, chase it. Run after it like you've never run before. Take the next ski lift to spiritual CandyLand. Indulge in the sugar rush. Jump off the Ferris Wheel just as it nears the peek. Climb the stairs in the seven layered skies. Become a hippie. Say outrageously trippy things that only you understand. Talk about G-d like you know Him. Don't mind the naysayers. If you want to fly, fly.
But as long as you have the impelling urge to fly you have not risen high enough. Go higher. Deeper. Closer.
The sign that you’ve achieved the G-dliness you were searching for is that you’re ready to fall back down again.
And when that feeling surrounds you, fall. Slowly. Don't leave pieces of yourself in the clouds. Come back to earth. Taking the G-dliness from your trip down with you as you go. Do as that awesome book suggests: Bring heaven back down to earth.
