Prajña or Pragya (Sanskrit: प्रज्ञ) as प्रज्ञा, प्राज्ञ and प्राज्ञा is used to refer to the highest and purest form of wisdom, intelligence and understanding. Pragya is the state of wisdom which is higher than the knowledge obtained by reasoning and inference.
The Sanskrit word प्रज्ञ (Prajña) is the combination of "प्र (pra-)" which prefix means – before, forward, fulfiller, and used as the intensifier but rarely as a separate word and "ज्ञ (jna)" which means - knowing or familiar with. प्रज्ञ (Prajña), meaning - wise, prudent, knowing, conversant with, is the root of प्राज्ञ (Prājña) meaning – wise, learned man, intellectual, clever, intelligence dependent on individuality; प्रज्ञा (Prajñā) meaning – intelligence, judgement, mental attitude, particular shakti or energy, insight, mental disposition, true or transcendental wisdom, awareness, mentality, understanding, discrimination, knowledge; and प्राज्ञा (Prājñā) meaning – understanding, intelligence.
In the state of deep sleep, the Atman, limited by Prana, the vital breath, is called Prājña.
There are a few Vedic Mantras which hint at Prājña, the wise and the learned intellectual. and so does Isha Upanishad which belongs to the Shukla Yajurveda.Dayananda Saraswati, translating and commenting on the Rig Veda, draws attention to a sage of the Rig Veda who tells us –
that the radiant one, who feeds and nourishes, who ensures births, who desires association with the learned, he surely soon gains wide varied knowledge (and becomes intelligent and aware).
And, to Vishwamitra who tells us -
that those who constantly strive to understand the ways and methods of the objective world and its origin and its being surely attain divinity (aishvarya).Sayana commenting on mantra III.27.7 observes that the most common meaning of māyā are prajñā ('intelligence') and kapata ('deceit') and that kratu of the compound-word Sukratu in mantra I.20.8 implies either karma (act) or prajñā ('knowledge').
