Show answer

Answer: (C) Only two pairs

The answer is (C) Only two pairs are correct (Pairs 2 and 3).

Pair 1 is WRONG:

Aryadeva was a BUDDHIST scholar (3rd century), NOT a Jain scholar.

He was a disciple of Nagarjuna and a key figure in Madhyamaka Buddhist philosophy.

Pair 2 is CORRECT:

Dignaga was a BUDDHIST scholar (6th century).

He was an Indian Buddhist monk and the founder of Indian logic (Hetu Vidya).

Born near Kanchipuram.

Pair 3 is CORRECT:

Nathamuni was a VAISHNAVA scholar.

He compiled the Nalayira Divya Prabandham (a collection of Tamil Vaishnava hymns) and is considered the first of the Sri Vaishnava Acharyas.

Key point:

Both Aryadeva and Dignaga were Buddhist scholars.

The trap is labeling Aryadeva as Jain — he was actually a direct disciple of Nagarjuna, one of the most important Buddhist philosophers.

Why this was asked

Aryadeva and Dignaga were both Buddhist scholars, but UPSC creates confusion by mislabeling Aryadeva as Jain - he was actually Nagarjuna's direct disciple in Madhyamaka philosophy.

The question tests whether students can distinguish between Buddhist and Jain philosophical traditions, which often get confused due to their simultaneous development in ancient India.

Aryadeva: Key Buddhist Scholar & UPSC Trap

Must know

Aryadeva was a Buddhist scholar (3rd century CE), NOT Jain

Direct disciple of Nagarjuna, founder of Madhyamaka philosophy
