Sri Rudram and the Purushasuktam are a pair of mellifluous Vedic hymns that can readily waft us to ethereal spiritual heights. Text with word-for-word meaning and brief notes from classic Sanskrit commentaries.
What I want is muscles of iron and nerves of steel, inside which dwells a mind of the same material as that of which the thunderbolt is made.
-Swami Vivekananda
