I want to know the answer to the following question:
Sanskrit is used as a pkilsosophical language in Hinduism, Buddhism, Jainism and which other religion?
All the background I'm provided with is that "Sanskrit (/ˈsænskrɪt/; Sanskrit: saṃskṛtam [səmskr̩t̪əm] or saṃskṛta, originally saṃskṛtā vāk, "refined speech") is the primary sacred language of Hinduism, a philosophical language in Buddhism, Hinduism, Sikhism and Jainism, and a literary language that was in use as a lingua franca in Greater India.". Is that enough to answer the question?
