We now ask: Which is the direct stream of the culture of the future? The Christ stream! It advances in a direct line. And what neighboring streams are there? We have first the Arabian stream, which flowed into the direct stream, paused for a time, and then received purification through the culture of the Renaissance. At present we are experiencing a renewed influx of the Buddha stream. When these facts are seen in their right light, we realize that we have to absorb certain elements out of the Buddha stream which until now could not be received into our Western civilization. We have to see how these elements of the Buddha stream must pass into the spiritual development of the West. — such things, for instance, as the idea of reincarnation and karma. These must be accepted. But one fact must be firmly impressed on our souls: All these neighboring streams will never be able to throw light on the central facts of our spiritual science. To question Buddhism or any other pre-Christian Oriental religion that may have appeared as a revival in our time concerning the Christ would be as sensible as for a European Christian to have questioned the Arabs of Spain concerning the nature of Christ!
From it you can find which is the direct path, the forward path. Everyone has the possibility of hearing of this path who understands the words from the Gospel of Matthew quoted at the end of the last lecture: “False Christs and false prophets will appear when people will say unto you: Lo, here is the Christ or lo, there! believe it not.”
