By Swami Harshananda
The Vaiśesikasutras of Kaṇāda or Aulukya who preceded Buddha has a commentary called Praśastapādabhāsya or Padārthadharmasañgraha by Praśastapāda. This commentary is more like a long independent essay on the Vaiśesikasutras than a regular bhāṣya.
The theories discussed in this commentary are:
- Several terms and concepts of the sutras
- Doctrine of creation
- Atoms in a molecule
- Transformation of colors by heat
Praśastapāda was the earliest writer on the Vaiśesikasutras after Kaṇāda and must have lived in the 5th or the 6th centuries A. D.
