All the spiritual teachers of humanity have told us the same thing, that the purpose of life on earth is to achieve union with our fundamental, enlightened nature. It says in the Upanishads:
There is the path of wisdom and the path of ignorance. They are far apart and lead to different ends. . . . Abiding in the midst of ignorance, thinking themselves wise and learned, fools go aimlessly hither and thither like the blind led by the blind. What lies beyond life shines not to those who are childish, or careless, or deluded by wealth.
