"At the end of this great symphony the different themes of the previous chapters are interwoven into one. The melodies of vision, love, and work in Eternity become one simple final strain of unearthly tenderness and beauty, the simple call of God to man: 'Come to me for thy salvation'. This is the symphony of the Bhagavad Gita. There are in it several themes which rise above the rest. There is Yoga. It is obvious that the spiritual Yoga of the Gita is love; but Yoga also means 'Samadhi', a state of inner communion with the object of contemplation. When this contemplation is turned upon any being or object in creation, we have poetry : when it is turned towards the Source of all creation we have Light, spiritual vision." Juan Mascaro Christmas Day 1960. Translator's introduction to The Bhagavad Gita, Copyright 1962. Penguin Books. Emphasis added.
