In plain words
Pradoṣe dīpakaś candraḥ prabhāte dīpako raviḥ trailokye dīpako dharmaḥ suputraḥ kuladīpakaḥ.
The sun, shining by day, shows the world to living beings. The moon, rising by night, shows living beings their paths. Dharma, lighting up the three worlds, teaches the ideal to all living beings. A good son shines as the lamp of his family through his exemplary conduct.
Kaṇāda saw, showed, proclaimed and taught the truth that wherever one looks there is nothing other than God. “Aṇoraṇīyān mahato mahīyān”: he discovered that what dwells in every atom is God Himself, and proclaimed that the atom is God. Without the atom there is no world. At the beginning of creation there was neither earth nor sky, neither sun nor moon, nor any stars. Pitch darkness had spread over everything. At such a time all the paramāṇus came together and settled into a very dense mass, and because of that a great heat arose. From that heat a tremendous sound arose, and that dense matter broke into pieces. It spread out in every direction. That itself became the root cause of creation. This, precisely, was Kaṇāda's experience. The sound that arose when it burst is itself the Praṇava. That itself is the Oṃkāra. That itself is the sound of the Praṇava. That itself is the first sound. It fills every place. From what did the Praṇava begin? It began from the paramāṇu itself. Kaṇāda taught that every human being must remember this sound of the Praṇava and so cross over.
Becoming subtle in the subtle atom, becoming mighty in the mighty thing, flourishing everywhere as the onlooker of all: the Praṇava is God, God is the Praṇava.
