This is a unique interpretation of the Isavasya Upanishad which is based on historical and linguistic realities and overcomes difficulties otherwise encounterd by other eminent scholars like Sankaracharya. Iswaran comes from the two sanskrit words Isa and paran, whch means Jesus is Lord. The word "Iswaran" came to mean God, only after the ministry of St.Thomas in India. This Upanishad is the doctrinal statement of the immanence and transcendence of Isa and his ability to provide release from death.
