Answer 1

Prajna can be interpreted as the wisdom beyond worldly reasoning and inference

Reference: https://en.m.wikipedia.org/wiki/Prajna_(Hinduism)

From Tattva bodha , SVSSS of HH Adi Shankaracharya, we see that the Abhimani(identify with) of sthula(gross) sharira is termed vishwan, and that of sukshma( subtle) sharira is termed Taijasan . Only when the Prani is in the state of sushupti transcending gross and subtle it is called prAjnyan.

Reference: TB verse 6. 3 chinmaya mission 3.1 Atha sushupti avasthaa kaa? Then what is the Deep Sleep State? .2 “Aham kimapi na jaanaami”, “I do not know anything”, .3 “Sukhena mayaa nidraa anubhuyate” “A good sleep was enjoyed by me”; .4 Iti sushupti avasthaa. such a state is called Deep Sleep. .5 Kaarana shareera abhimaani aatmaa “Praajna” iti uchyate. Identifying Itself with the causal body, the Self is called “PRAJNA”

Reference: Bhagavad Gita 2.11

aśhochyān-anvaśhochas-tvaṁ prajñā-vādānśh cha bhāṣhase gatāsūn-agatāsūnśh-cha nānuśhochanti paṇḍitāḥ

Here Prajna Vada , is the wisdom beyond vyavaharik (worldly) inference

Reference: Bhagavad Gita 2.54 sthita-prajñasya kā bhāṣhā samādhi-sthasya keśhava sthita-dhīḥ kiṁ prabhāṣheta kim āsīta vrajeta kim

Sthitha Prajna is steady supreme wisdom which is transcendent

PrajnA is also seen in Mahayana buddism vocabulary , as prajna parimitha meaning perfect wisdom beyond worldly inference
