Sanskrit is a perfect language and is therefore very glorious.

In Sanskrit, there are definite rules that regulate poetry; rhyme and meter are not written whimsically, as in much modern poetry.

According to learned scholars, there are three different sources of knowledge, which are called prasthana-traya. According to these scholars, Vedanta is one of such sources, for it presents Vedic knowledge on the basis of logic and sound arguments. In the Bhagavad-gita (13.5) the Lord says, brahma-sutra-padais caiva hetumadbhir viniscitaih: "Understanding of the ultimate goal of life is ascertained in the Brahma-sutra by legitimate logic and argument concerning cause and effect." Therefore the Vedanta-sutra is known as nyaya-prasthana, the Upanisads are known as sruti-prasthana, and the Gita, Mahabharata and Puranas are known as smrti-prasthana. All scientific knowledge of transcendence must be supported by sruti, smrti and a sound logical basis.

But as is seen from the verse below, Sanskrit is not so important without devotion.
"[Lord Krsna said:] 'Even though a person is a very learned scholar of the Sanskrit Vedic literatures, he is not accepted as My devotee unless he is pure in devotional service. However, even though a person is born in a family of dog-eaters, he is very dear to Me if he is a pure devotee who has no motive to enjoy fruitive activity or mental speculation. Indeed, all respects should be given to him, and whatever he offers should be accepted. Such devotees are as worshipable as I am.'

Therefore, Sankaracarya wrote at the end:
bhaja govindam bhaja govindam
bhaja govindam mudha-mate
sampräpte sannihite kale
na hi na hi raksati dukrn-karane
"You intellectual fools, just worship Govinda, just worship Govinda, just worship Govinda. Your grammatical knowledge and word jugglery will not save you at the time of death."
Mayavadi sannyasis are always very puffed up because of their knowledge of Sanskrit and because they belong to the Sankara-sampradaya. They are always under the impression that unless one is a brahmana and a very good Sanskrit scholar, especially in grammar, one cannot accept the renounced order of life or become a preacher. Mayavadi sannyasis always misinterpret all the sastras with their word jugglery and grammatical compositions, yet Sripada Sankaracarya himself condemned such jugglery of words in the verse prapte sannihite kale na hi na hi raksati dukrn karane. Dukrn refers to suffixes and prefixes in Sanskrit grammar. Sankaracarya warned his disciples that if they concerned themselves only with the principles of grammar, not worshiping Govinda, they were fools who would never be saved. Yet in spite of Sripada Sankaracarya's instructions, foolish Mayavadi sannyasis are always busy juggling words on the basis of strict Sanskrit grammar.
