śivaḥ - Lord Śiva; śakti-yuktaḥ - associated with material nature; śaśvat - eternally; tri-liṅgaḥ - in three features; guṇa-saṁvṛtaḥ - covered by the modes of nature; vaikārikaḥ - one is called vaikārika; taijasaḥ ca - another is called taijasa; tāmasaḥ ca - as well as tāmasa; iti - thus; aham - egotism; tri-dhā - three kinds.

“ ‘The truth about Lord Śiva is that he is always covered with three material coverings — vaikārika, taijasa and tāmasa. Because of these three modes of material nature, he always associates with the external energy and egotism itself.’
