From a nondual Buddhist point of view the Buddha never concluded his journey, since it never actually started. There was never, in reality, either a journey or anyone who could possible travel it.
It is said that even Buddhas, fully awakened people, continue to work on themselves. There is no limit to your level of awareness, your buddhahood. There never can be, since full awareness necessarily includes the awareness that there never were limits, nor levels, nor awareness, and that that there was never anything that could possibly be full or empty Even these characteristics never so much as hint of real existence.
By being as you are and doing what you are doing, you achieve all, since nothing more can conceivably be asked of you. This is complete self-fulfillment, where nothing is missing and there is nothing you need to remove. Through study and meditation, as you begin to realize that you are already as you are and are already doing exactly what you are doing, it becomes clear that there is no other possibility.
Enlightenment, becoming a Buddha, fully awakened, is no more than this:
- Find a teacher.
- Make yourself some quiet time every day to remember what you forgot – that things are as they are.
- Spend time with like-minded friends who can support you on you spiritual journey.
