Detailed meaning from the book Prayer Guide by Swami Dayananda
Rudra is the one who is known through the sāstras or Vedas. The word 'Rudra' means the one who destroys samsāra or ajñāna, ignorance. The other meaning is the one into whom the whole world is resolved. When the Lord absorbs into himself everything that is projected, he is Rudra. That is why you will see Lord Siva sitting in meditation. Everything is absorbed into him; the whole world of time and space collapses into him. The limitless conscious being, saccidānanda-vastu, who is Isvara as the one who brings into manifestation, sustains and resolves the world, srsti-sthiti-laya-kartr, is called Rudra, in the function of resolving. He is the one whose grace is invoked for the removal of ignorance. This Rudra is puruşa, who is pūrņa or limitless. What kind of puruşa is he?
Tatpuruṣāya, tasmai puruṣāya which is to be taken as tam puruşam. It is told in the śāstras that Isvara, is the prathama-puruşa, the first person. In English grammar what we call the third person is the first person in Sanskrit. He is the first one and everything comes from him. We pray to know that being, puruşa, who is pūrņa, limitless, and who is revealed by the sāstra. Puruṣāya is construed as puruşam, the accusative case.
Vidmahe, may we know or come to know. The verb is in the plural. This is a gayatri-mantra. In all gayatri mantras, like this one, the verb is in the plural. Why do we say 'we' when it is 'I' who wants to know? This is because we include others in our prayer. May we know that puruşa who is limitless.
Mahadevāya dhimahi. Dhimahi means we meditate upon. We meditate upon that Lord Mahadeva who is mahān, limitless, and who is all-knowledge, devā, the Lord of all Lords and the Lord of all devatās like Indra, Varuna and so on.
Tanno rudraḥ pracodayāt: Tat, that Rudra or Mahādeva, who we want to know and upon whom we meditate, naḥ pracodayāt, may he impel us. May he set our minds in the proper direction to enable us to discover what the truth is, and what the Lord is. Here one meaning of pracodayet is, may he impel the mind on the proper course of action. We can also understand it to mean pracodanam kuryāt. Pracodana means dyotana, illumination. May he endow our minds with lustre and clarity, may he make all our thoughts brilliant or effulgent!
