The Upanishads represent a foundation for Indian philosophies. Using complex linguistic devices such as puzzles, paradoxes, metaphors, dramatic personae and word-play, they force an engagement of consciousness. The Isha Upanishad is among the most concise and complex of Upanishads, and one of the most diversely interpreted. Sri Aurobindo wrote a commentary on this Upanishad, seeing it as embodying a problem of becoming, the attainment of a consciousness in which unity and multiplicity are identical and do not erase each other. Drawing on this commentary as well as on the larger body of Sri Aurobindo’s works, this book presents four meditations on the Isha Upanishad. In the spirit of the Upanishads, these meditations are both presentations and contemplations meant to aid subjective orientation and alignment. At the same time, they trace the philosophical vision of Sri Aurobindo.
