। ॥ १८ ॥
In plain words
You swallowed the poison to spare the world — who here is your equal, O Lord? Sāmba, Sadāśiva, Śambhu, Śaṅkara: your two feet are my refuge.
Close to the Sanskrit
The poison, for the benefit of the world, was swallowed by you; who here is equal, O all-pervading one? O Sāmba, O Sadāśiva, O Śambhu, O Śaṅkara — the pair of your feet is refuge for me.
