utsāho balavān ārya nāsty utsāhāt paraṁ balam
utsāho balavān ārya nāsty utsāhāt paraṁ balam |
sotsāhasya hi lokeṣu na kiñcid api durlabham ||
(Rāmāyaṇa: Kiṣikindhā-kāṇḍa, 4.1.121; cited in Mahāsubhāṣita-saṅgraha: 6673)
[Lakṣmaṇa to Rāma while distraught after the abduction of Sītā:] “O noble one, enthusiasm is powerful. Nothing is more powerful than enthusiasm. Indeed, there is nothing unattainable in all the worlds for one who has enthusiasm.”
