ēvaṁ pahāṇēṇa viṇā na kajjaṁ, uvēi siddhi vavasijjamāṇaṁ
jahā nisā rikkha-gahāṇuvannā, na hōi jōhāvimalaṁsuhīṇā

Thus without an eminent leader an undertaking, though being pursued, does not achieve success, / just as a night endowed with stars and planets is not [bright] without the pure moonbeams.
