Often because of our limitations Puruṣa is often recognised or identified with Ahaṃkāra as the ‘I’ am principle. This is why Buddhi is regarded as the highest principle as one needs Buddhi or the discriminative ability to recognise this and see beyond it to Puruṣa.

Next comes a definition of intellect.
