11. When going to cross (the river), he addresses (the ship): 'The well-protecting' (Vâg. Samh. XXI, 6).
12. A forest (through which he is wandering) he addresses: 'Adoration to Rudra who dwells in the forests. Make me arrive safely.'

367:19 The play on words is untranslatable; 'jackal' is sivâ, 'friendly,' sivah.
367:20 I do not know the meaning of kârkârinah. Gayarâma takes it for a genitive standing instead of an accusative, and explains it by asmadbâdhakam.
