Bhagavad Gita · Raja Vidya Raja Guhya YogaChapter 9, Shloka 14 (9.14)

Shankaracharya. Satataṃ sarvadā bhagavantaṃ brahma-svarūpaṃ māṃ kīrtayantaḥ — always singing the praise of me, whose nature is Brahman; yatantaś ca indriyopasaṃhāra-śama-dama-dayāhiṃsādi-lakṣaṇaiḥ dharmaiḥ — striving with virtues such as restraint of the senses, calm, compassion and non-violence (ahimsa); namasyantaś ca māṃ hṛdayeśam ātmānam — bowing to me, the Lord of the heart, the self.

Acharya Ramanuja — a living picture of devotion. Mat-kīrtana-yatana-namaskāraiḥ vinā kṣaṇāṇu-mātre api ātma-dhāraṇam alabhamānāḥ — those who cannot survive even the smallest fraction of a moment without singing my praise, striving and bowing down; mad-guṇa-viśeṣa-vācīni man-nāmāni smṛtvā pulakita-sarvāṅgāḥ harṣa-gadgada-kaṇṭhāḥ śrī-rāma-nārāyaṇa-kṛṣṇa-vāsudeva ity evamādīni satataṃ kīrtayantaḥ — remembering my names, which speak of my qualities, their whole bodies thrilling, their throats choked with joy, they sing without pause names like "Shri Rama, Narayana, Krishna, Vasudeva"; yatantaḥ mat-karmasu arcanādikeṣu … bhavana-nandana-vana-karaṇādikeṣu — striving in works such as worship and praise, and building temples and gardens; aṣṭāṅgaiḥ acintita-pāṃsu-karddama-śarkarādike dharā-tale daṇḍavat praṇipatantaḥ — prostrating full length on the ground with all eight limbs, without a thought for dust, mud or gravel.
