Meaning

'Om Tat Sat'—that's the ultimate three-word drop about Brahman. It's how the Brahmanas, the Vedas, and all the rituals got started, way back when.

Commentary

Okay, so like, 'Om Tat Sat' is, like, the OG mantra, the ultimate vibe check for the entire universe. 'Om' is the ultimate truth, the real deal. 'Tat' is that which is beyond definition, that which cannot be put into words. And 'Sat' is pure, unadulterated reality. The Supreme Being, the ultimate source of everything, is beyond labels and categories. But, like, the Vedas tried to give it a name, you know? It's like, a newborn baby doesn't have a name, but once they get one, they respond to it. People who are, like, totally stressed out about life, they call out to the Divine, they give it a name. When you call out to Brahman using this name, it's like, the hidden stuff gets revealed. These three words have, like, major power. The vibes they give off awaken your inner divinity and get a response from the Cosmic Being. If a ritual or something is, like, totally messed up, saying 'Om Tat Sat' fixes it. You start all your rituals, studying, meditating, everything with 'Om' or 'Om Tat Sat'. If you remember these mantras while doing rituals, all the obstacles disappear. 'Om Tat Sat' is the ultimate three-word description of Brahman, according to the OG Brahman experts. The power of creation comes from this mantra. When the Creator meditated on it, they got the power to create everything. Then they created the Brahmanas, gave them the Vedas as their guide, and told them to do all the rituals and stuff. 'Pura' means way back when, at the very beginning of creation.
