Sometimes we see a picture of Lord Śiva engaged in meditation. This verse explains that Lord Śiva is always meditating upon Lord Saṅkarṣaṇa in trance. Lord Śiva is in charge of the destruction of the material world. Lord Brahmā creates the material world, Lord Viṣṇu maintains it, and Lord Śiva destroys it. Because destruction is in the mode of ignorance, Lord Śiva and his worshipable Deity, Saṅkarṣaṇa, are technically called tāmasī. Lord Śiva is the incarnation of tamo-guṇa. Since both Lord Śiva and Saṅkarṣaṇa are always enlightened and situated in the transcendental position, they have nothing to do with the modes of material nature — goodness, passion and ignorance — but because their activities involve them with the mode of ignorance, they are sometimes called tāmasī.
