Any action or reaction of a part of a body becomes a cognizable fact to the embodied soul. Similarly, since the creation is the body of the Absolute Truth, then everything in the creation is known to the Absolute, both directly and indirectly.
In the śruti-mantra it is stated that the absolute whole, or Brahman, is the ultimate source of everything. Everything emanates from Him, everything is maintained by Him, and at the end everything enters into Him again. That is the law of nature. This is confirmed in the smṛti-mantra. There it is said that at the beginning of Brahmā’s millennium the source from which everything emanates is the Absolute Truth, or Brahman, and that at the end of that millennium the reservoir into which everything enters is that same Absolute Truth. Material scientists haphazardly take it for granted that the ultimate source of this planetary system is the sun, but they are unable to explain the source of the sun.
