No, this is not the Buddha:
If you are quiet enough, you will hear the flow of the universe. You will feel its rhythm. Go with this flow. Happiness lies ahead. Meditation is key.
I have absolutely no idea where this one originates from. It seems to be quite recent, and hasn’t made its way into any books that are indexed by Google Books (one of my main research tools).
It’s on a number of websites, and graphics containing this quote are common on Pinterest. So far the oldest instance of it I’ve seen is from May 5, 2012, in a Facebook post. It was undoubtedly around before then, though.
The Buddha did not use metaphors like “the flow of the universe.” He didn’t tell us to go with the flow. He did however talk about streams and rivers in a metaphorical way. Here’s a lovely example:
Know from the rivers
in clefts and in crevices:
those in small channels flow noisily,
the great flow silent.
Whatever’s not full makes noise.
Whatever is full is quiet.
This next one is less appealing to our modern sensibilities:
Whatever streams are in the world, it is mindfulness that obstructs them and restricts them, and by wisdom they are cut off.
The “streams” here are the currents of craving that flow in the mind. It’s as if we’re swept along by these streams:
The misguided man in whom the thirty-six currents of craving strongly rush toward pleasurable objects, is swept away by the flood of his passionate thoughts.
That one’s from the Dhammapada, verse 339.
The 36 streams are three types of craving (for experiences to happen, to continue, and to end) combined with the six sense-channels through which the cravings flow (mind being the sixth sense).
Accordingly, the first level of realization is the “stream-winner” (sota-panna), who has broken through the fetters of 1) belief in a separate and permanent self, 2) of doubt in the attainment of awakening, and 3) of using spiritual practices as a way to avoid realization.
