Bhagavad Gita · Vishvarupa Darshana YogaChapter 11, Shloka 55 (11.55)

Shankaracharya. The preface (at the end of 11.54): adhunā sarvasya gītāśāstrasya sārabhūtaḥ arthaḥ niḥśreyasārthaḥ anuṣṭheyatvena samuccitya ucyate — now the essence of the whole teaching of the Gita, for the sake of liberation, is stated together in a form to be practised; karoti bhṛtyaḥ svāmikarma, na tu ātmanaḥ paramā pretya gantavyā gatir iti svāminaṃ pratipadyate — a servant does his master's work but does not take the master as his supreme goal; this devotee does; saṅgavarjitaḥ dhanaputramitrakalatrabandhuvargeṣu; and most important of all: nirvairaḥ nirgatavairaḥ sarvabhūteṣu śatrubhāvarahitaḥ ātmanaḥ atyantāpakārapravṛtteṣv api — free of hostility towards all beings, even towards those who are bent on doing him the greatest harm.

Acharya Ramanuja. vedādhyayanādīni sarvāṇi karmāṇi madārādhanarūpāṇi iti yaḥ karoti — one who does all actions as worship of me; why no enmity? Three reasons: svaduḥkhasya svāparādhanimittatvānusaṃdhānāt — from understanding that the cause of one's own suffering is one's own mistakes; sarvabhūtānāṃ paramapuruṣaparatantratvānusaṃdhānāt — from knowing that all beings depend on the Supreme Person; ca sarvabhūteṣu vairanimittābhāvāt teṣu nirvairaḥ — so there is no reason for enmity.

Madhusudana Saraswati. sarvasya gītāśāstrasya sārabhūto 'rthaḥ — the essence of the whole teaching of the Gita; and "nirvaira" = apakāriṣv api dveṣaśūnyaḥ — free of hatred even towards those who do harm.

Shridhar Swami. sarvaśāstrasāraṃ paramaṃ rahasyaṃ — the essence of all scriptures, the supreme secret.

Shankaracharya — further. A fine distinction about "mat-parama": karoti bhṛtyaḥ svāmikarma? na tu ātmanaḥ paramā pretya gantavyā gatir iti svāminaṃ pratipadyate — a servant does his master's work but does not take the master as his own supreme goal; the devotee both does the Lord's work and takes the Lord alone as the supreme goal.
