The Realisation of the Absolute : 4.6.1.

Chapter 4: The Nature of Reality : 6.1.
6. The Power of Brahman - 1.

Further if there is actual creation, how do the Upanishads reconcile this with their position that on the realisation of the Absolute there is disappearance of objectivity?
A real thing can never be negated its existence.
Only a false notion can be removed by knowledge.
The creative act cannot be called even an Idea or a Thought of the Absolute, for in it thought and reality are one.

If creation is different from the Absolute, it cannot exist.
If it is identical with it, the Absolute alone is, and not anything produced.
Hence, from the highest standpoint, creation must be false, a mere myth.
This mysterious juggle, which, though not real, appears to screen the Absolute Consciousness and project an objective consciousness, is the so-called Power of Brahman, and its appearance is suggested in the Upanishads.

Indra is said to appear in many forms through his juggling powers (Brih. Up., II. 5.19).
The Svetasvatara Upanishad says that the Supreme Being is the juggler and the universe of creation is His jugglery (IV. 10).
