An underwhelming experience from the poetic perspective, even when compared to Shankara's Atma Bodha. What is interesting here is Shankara (or his later followers)'s refutation of Buddhist shunyata using Vedic scriptures (shruti) as a source, but then a volte face where, verse 90 onwards, he goes against the emphasis on the persistence of karma even after self-realisation in the very same scriptures. Here, he provides the (apparently) contradictory doctrine that only the scriptures that contribute to jnana-yoga should be followed.
Note also the conclusion, which tries to reinterpret Patanjali's Yoga Sutras by redefining the 8 limbs from the perspective of jnana alone. He literally refers to the common understanding of pranayama as "torturing the nose by the ignorant". In my opinion, his strict emphasis on jnana even in yoga ignores the role of the mind and body as instruments towards self-realisation. To be fair, he does provide a role for hatha-yoga in the last verse, if only for mind and body purification to help in self-realisation.
More broadly, though, after my recent reading of more realistic Advaitins like Sri Aurobindo and Swami Medhananda's writings and talks on Sri Ramakrishna and Swami Vivekananda, I cannot stomach Shankara's extreme Advaita (something that I could do when I was 17). It is cold and lifeless, like its nirguna Brahman. Maybe I will come back to this someday when I again find myself in the nihilistic, agnostic void which Shankara fills so masterfully.
