Vivekachudamani Verses 56-61

Notes: None of these, if practised mechanically, will bring on the highest knowledge—the absolute identity of the Jiva and Brahman—which alone, according to Advaita Vedanta, is the supreme way to liberation.
‘Yoga’ may mean Hathayoga which strengthens the body.
According to the Sankhya philosophy liberation
is achieved by the discrimination between Parasha and Brakriti. The Purusha is sentient but inactive, and all activity belongs to Prakriti, which is non-sentient, yet independent of the Purusha. The Sankhyas also believe in a plurality of Purushas. These are the main differences between the Sankhya and Vedanta philosophies.
Work—Work for material ends, such as getting to heaven and so forth, is meant.
Compare Svetasvatara Upanishad III. 8.—‘Seeing Him alone one transcends death, there is no other way.’

Notes: Book-learning to the exclusion of realisation is deprecated in this and the following Slokas.
Loud speech.—Speech is divided into four kinds according to its degree of subtlety. Vaikhari is the lowest class, and represents articulate speech. Hence, dabbling in mere terminology is meant.

Notes: Prior to realisation, mere book-learning without Discrimination and Renunciation is useless as it cannot give us Freedom, and to the man of realisation, it is all the more so, as he has already achieved his life’s end.
