In plain words
When Death's messengers are standing right beside me, hideous, their words brutal — how will my mind hold steady at the lotus of your feet? Salutations to you, Śambhu.
Close to the Sanskrit
When the messengers of Death — savage of speech, terrifying — will be close beside me, then how shall my mind, abiding at the lotus of your feet, be unwavering? Let there be salutation to you, O Śambhu.
