The Absolute Truth can be compared to the sun, which is appreciated in terms of two relative truths: reflection and darkness. Darkness is the absence of sunshine, and a reflection is a projection of sunlight into darkness. Neither darkness nor reflection has an independent existence. Darkness comes when the sunshine is blocked. For example, if one stands facing the sun, his back will be in darkness. Since darkness stands in the absence of the sun, it is therefore relative to the sun. The spiritual world is compared to the real sunshine, and the material world is compared to the dark regions where the sun is not visible.
When the material manifestation appears very wonderful, this is due to a perverted reflection of the supreme sunshine, the Absolute Truth, as confirmed in the Vedānta-sūtra. Whatever one can see here has its substance in the Absolute. As darkness is situated far away from the sun, so the material world is also far away from the spiritual world. The Vedic literature directs us not to be captivated by the dark regions (tamaḥ) but to try to reach the shining regions of the Absolute (yogi-dhāma).
