Lyric discussion by eclecticears 

There are many symbols in these verses which are often described by adepts of spiritual meditation, so it makes perfect sense that these lyrics were taken from Chinese Taoist poetry as described by Rbuzz above. Universal out of body experiences within meditation as described by spiritual seers include a stage where one penetrates through the middle of a spiritual sun, which leads to a higher stage of spirituality. There lies the basic concept behind the song: Setting the controls (spiritual preparation/meditation) to reach the heart of the sun.

Here are some examples in the lyrics describing the concept of meditation: “Little by little the night turns around” (and) "Breaking the darkness, waking the grapevine” These lines refer to the meditation process, which begins with inner darkness and slowly expands to inner light. This breaking of darkness 'wakens the grapevine' which gives spiritual intoxication from it's wine.

“Love is the shadow that ripens the wine" This is reference to feelings of love in meditation which ripen the wine (wine in spiritual poetry being a symbol of spiritual intoxication).

Other key ideas in meditation are referred to such as “watching the watcher”, and “making the shape of his question to heaven” (heaven being available when he penetrates through the heart of the sun)
