In plain words
Again, with a fullness of devotion, he says, to bow down: Homage to Śaṃbhu, the great Swan, whose one dwelling is the clear mind of the good, His limbs white with abundant ash. Homage to Śaṃbhu, the great Swan. His being a swan is as before; His greatness is in relation to all the Rudras who are knowers of the field. For all knowers without exception are swans, haṃsa, because their nature is letting go and taking up, hāna and samādāna, in the form of the emanation and withdrawal proper to them; but Śaṃbhu makes the emanation and withdrawal even of them, and so He is the great Swan. For this very reason, in the venerable Svacchanda, “Śiva by dharma, but the Swan …” having begun so, “The Self indeed is the Swan …” and so on, is said. What kind of Śaṃbhu? ‘Clear’, that is, free of doubt about the real meaning through the fullness of devotion to You: the ‘mind’, that is, the thought, of ‘the good’, that is, of those whose conduct is excellent, consisting in meditation on You; to Him who ‘dwells’ in that ‘alone’, that is, who habitually shines forth there with His Self unconcealed; and so too to Him whose ‘limbs’, that is, own form, which is the form of the powers whose nature is knowledge and action, are ‘white’, sita, that is, bound, with ‘abundant’, that is, great, ‘ash’, bhūti, that is, glory, which is māyā, the variety of the universe. And a great swan, too, dwelling in the lake called the clear Mānasa, has white limbs, as if with abundant ash: that is the resonating meaning.
