स सूर्याय महेन्द्राय पवनाय स्वयंभुवे।भूतेभ्यश्चाञ्जलिं कृत्वा चकार गमने मतिम्।।।।

With folded hands he offered reverent salutations to the Sun, to Mahendra (Indra), to the Wind-god, to Svayaṃbhū (Brahmā), and to the hosts of beings; then he set his mind upon departure.
Offering salutations with folded palms to the Sun-god, to Mahendra, lord of the gods, to the wind-god, to the Creator Brahma and to all the attendants of lord Siva, made up his mind to proceed (to Lanka).
Dharma is humility and right alignment: before undertaking a perilous task, Hanumān honors divine order and seeks auspiciousness, showing that power should be guided by reverence and propriety.
Immediately before setting out for Laṅkā, Hanumān offers salutations to major deities and spiritual hosts, then fixes his intention to go.
Vinaya (humility) joined with niścaya (firm resolve): he bows first, then acts decisively.
