The Gayatri mantra that originates from the Rig Veda is unique in that it glorifies the one God. In Guru's ‘Daiva Dasakam’ (Ten Verses on God), a universally significant prayer. comparable to the Gayatri mantra, emerges. If devotion is deemed the most appropriate means for alleviating suffering and achieving self-realization, Guru instructs that the devotee must first abandon ego and strive for God-realization. He conceptualizes the world as a sorrowful ocean of ‘samsara’ (the cycle of birth and death), the devotee as a helpless soul trapped within it, God as a powerful captain, and the divine abode as a ship. Just as Guru dispels the darkness of ignorance, God possesses the power to eliminate the fear of worldly sorrow that grips the devotee. By concentrating our minds, we can attain eternal bliss. Guru illustrates this interconnectedness: just as the ocean, waves, wind, and depth are inseparable, so too are ‘Maya’ (illusion), divine glory, "we”, and "you”.
It was through the strength of his Advaita Darshanam that Guru envisioned the ideal of ‘Do not cause any harm to even an ant’. This profound Advaita insight, combined with his boundless compassion for all living beings, fueled his powerful stance against social slavery and the suffering of his fellow humans. The non-violence and compassion characteristic of those who have realized the non-dualist truth are prominently displayed in Guru's life and teachings. While traditional Advaita Vedanta often defines Atman by what it is not, Narayana Guru uniquely defines what Atman is. In ‘Atmopadesa Shatakam’, Guru describes Atman as knowing itself by being in darkness and knowing other things by illuminating them. ‘Vedanta Sutram’ further states that Atman is inherently luminous, asserting that the knowledge of its luminosity is self-evident.
Guru presented the secret of Advaita, as he comprehended it, in his distinct style and with ascientific approach. Muni Narayana Prasad aptly observes that Guru's philosophy was notmerely ‘Advaita Vaada’ (Theory of Advaita), but rather an expansive ‘Advaita Darshanam’ (Vision of Advaita).
