In plain words
Śruti says, 'Having examined the worlds... Brahmavidyā in truth.' When Vidyā—knowledge—is firmly grasped, it serves one's highest good and keeps the teaching alive. That continuity benefits living beings, like a boat for someone who longs to cross a river. Śāstra also says, 'Even if one gave him this whole earth, filled with wealth and ringed by waters, this alone is greater.' Knowledge is not gained without an Ācārya: 'A person with an Ācārya knows'; 'Vidyā known from an Ācārya alone'; 'The Ācārya carries one across'; and 'Right Jñāna is called a raft here.' Smṛti agrees: 'They will teach you Jñāna.'
Close to the Sanskrit
And Śruti says: 'Having examined the worlds... Brahmavidyā in truth.' Vidyā—knowledge—firmly grasped serves one's highest good and the continuity of the teaching. The continuation of Vidyā is for the benefit of living beings, like a boat for one who wishes to cross a river. And Śāstra says: 'Even if one gave him this earth, filled with wealth and encircled by waters, this alone is greater than that.' Knowledge cannot otherwise be attained, as the Śrutis declare: 'A person with an Ācārya knows'; 'Vidyā known from an Ācārya alone'; 'The Ācārya carries one across'; and 'Right Jñāna is here called a raft'; and as Smṛti says, 'They will teach you Jñāna.'
