What is the nature of Krishna's relationship with Draupadi and the spiritual union of Vasudeva and Devaki?

According to Osho, Krishna’s essential relating, including with Draupadi, is on the plane of the soul: true union is ‘spiritual intercourse,’ where bodies merely follow like shadows, free of lust. Thus Krishna’s birth from Vasudeva and Devaki is the fruit of a soul-level meeting; and beside such Everest-like heights, even their children seem historically small—not valueless, but eclipsed by the peak they stand near.
