Whole days go by like one instant for the man whose only hunger is a single moment of service at your feet, Śiva — O Śiva! Sāmba, Sadāśiva, Śambhu, Śaṅkara: your two feet are my refuge.
Close to the Sanskrit
Like a moment he will pass the days — he who is eager for a single moment of service at your feet, O Śiva, O! Sāmba, Sadāśiva, Śambhu, Śaṅkara: my refuge is the pair of your feet.
