Introduction by Acharya Madhva
Īśā.Bhāshya 00
Salutations to the eternal one who sustains the permanent and the impermanent universe, to the embodiment of knowledge, to the one with complete bliss, to lord Hari who is the enjoyer of all sacrifices.
Savayambhu Manu worshipped the divine lord Vishnu by Īshavasya Upanishad mantras, as stated in Brahmānda and Bhāgavata Purāna.
॥हरिः ॐ॥
Lord Hari is only Ōm!
नित्यानित्यजगद्धात्रे नित्याय ज्ञानमूर्तये। पूर्णानन्दाय हरये सर्वयज्ञभुजे नमः ॥१॥
Solutions to the eternal one who sustains the permanent and the non-permanent universe, to the embodiment of knowledge, to the one with complete bliss, to lord Hari who is the enjoyer of all sacrifices.
यस्माद् ब्रह्मेन्द्ररुद्रादिदेवतानां श्रियोऽपि च। ज्ञानस्फूर्तिः सदा तस्मै हरये गुरवे नमः ॥२॥
I solute to that lord Hari, who is the inspiration of knowledge to Brahma, Indra, Rudra, and others, and even goddess Shri and also to my Guru.
स्वायम्भुवो मनुः एतैःमन्त्रैः भगवन्तम् आकूतिसूनुं यज्ञनामानं विष्णुं तुष्टाव।
Savayambhu Manu worshipped the divine lord Vishnu, son of his daughter Ākuti, who also bears the name Yajna by these Upanishad mantras.
स्वायम्भुवः स्वदौहित्रं विष्णुं यज्ञाभिधं मनुः। ईशावास्यादिभिर् मन्त्रैः तुष्टावावहितात्मना। रक्षोभिरुग्रैः सम्प्राप्तः खादितुं मोचितस्तदा। स्तोत्रं श्रुत्वैव यज्ञेन तान् हत्वाऽवध्यतां गतान्। प्रादाद्धि भगवान् तेषाम् अवध्यत्वं हरः प्रभुः। तैर्वध्यत्वं तथाऽन्येषाम् अतः कोऽन्यो हरेः प्रभुः॥
"Manu, the self-existent, worshipped with a concentrated mind, his own daughter son lord Vishnu, known as Yajna, with mantras like the Isha Upanishad. Then, he was approached by fierce demons to devour. Having heard the hymn, the divine Lord granted Manu immortality after killing the demons by the sacrifice. Indeed, it is Lord Shiva, who gave those daemons immortality. Who else other than lord Hari, the master of Lord Shiva can grant mortality to them?"
इति ब्रह्माण्डे।
- stated thus in Brahmānda Purāna.
भागवते च अयमेव अर्थ उक्तः॥
This very meaning is stated in the Bhagavata Purana as well.
