Linguistically and in the context of the Upanishads, the puruṣa is the Self. This is also how Sri Aurobindo translates puruṣa. Amongst philosophers with a Sāṁkhya orientation, it is not unusual, however, to see the word puruṣa translated as "consciousness". What links the two is that our Self is the carrier and the centre of our consciousness. Consciousness and identity are in fact so closely related that there is not much difference for example between a quality of someone's consciousness and a quality of his self.
