Question
Do the different schools of thought in Hinduism believe that where way of getting moksha is the only correct way and others are
wrong?
Answer
The various Vedantic sects are divided into those that consider Brahman to be different from Jiva (dualists) and those that consider them to be identical (non-dualists). Most of these schools acknowledge that people following other schools can attain high spiritual states. What nondualists are not sure of is whether dualists must have the experience of Nirvana. Similarly dualists are not sure if nondualists can experience the intense bliss enjoyed by the dualists.
Mahima: "I have a question to ask sir. A lover of God needs Nirvana (total annihilation of ego -- the ideal of the jnani) some time or other, doesn't he?
Master: "It can't be said that bhaktas need Nirvana. According to some schools there is an eternal Krishna and there are His eternal devotees. Krishna is spirit embodied, and His abode is also spirit embodied. Krishna is eternal and His devotees are also eternal."
The Gospel of Sri Ramakrishna, Chapter 41, At Ram's House
