Commentary by Swami Tejomayananda. The Vibhishan Geeta is found in Lanka Kanda of Sri Ramcharit Manas by Goswami Tulasidas. Lord Rama assured Vibhishana when the latter lovingly expressed his doubt about Rama's victory (who was bare footed and without any armor) over Ravana who was in a special war chariot well protected by sophisticated weapons. Pages 46.
