Vibrations of a Master ~ The Essence of the Bhagavad Gita, class 60, verses 5:16-20
Why has the Gita outlasted so many other scriptures? Because the consciosusness of a God-realized master is accessible to us across all time and space. Krishna put forth his consciousness though these words and that's what makes these words so perennially profound. These verses talk about what makes great souls so even-minded.
