More on “internal, external, or both” as regards Śaṅkarācārya’s commentary on the Investigation of the Three States.
I’m about 25% through the Investigation of the Three States. I was intrigued by the commentary on v4.3.2. That verse:
- ‘Yājñavalkya, what serves as the light for a man?’ ‘The light of the sun, O Emperor,’ said Yājñavalkya, ‘it is through the light of the sun that he sits, goes out, works and returns.’ ‘Just so, Yājñavalkya.’
Then the commentary (my italics):
Question: What difference does it make if he uses a light extraneous to his body or one forming a part of it?
Reply: Listen. If it is decided that he by his very nature has to use a light extraneous to his body, then with regard to the effects of a light that is invisible we shall infer that they are also due to an extraneous light. If, on the other hand, he acts through a light not extraneous to the body, but part and parcel of himself, then, where the effects of a light are visible, although the light itself is invisible, we can infer that the light in question must be an inner one. If, however, there is no restriction as to whether the light which a person uses is within or without himself, then there is no decision on the matter of the light.
Is it possible that the somewhat enigmatic refrain in the satipaṭṭhānasutta (MN10, DN22) is a kind of counterpoint?
And so they meditate observing an aspect of the body internally, externally, and both internally and externally.
That is, the Buddha teaches there is no meaningful distinction between whether, in this case, sati is maintained through external or internal means (or both). It is sati regardless.
Versus the Upanishad commentary which is decidedly in favor of cognizing the “internal light” as means of reaching the Supreme Self. In fact, further down the commentary is the firm disputation of the Buddhist response:
…they deny the light of the self as distinct from the body and illumining the consciousness of the intellect.
I realize, at the end of the day, that the MN10/DN22 refrain “says what is says” and so we don’t have to impute any more meaning to it than that.
Still, from a contextual perspective, it is intriguing to me that this may have been an origin of the Buddha’s teaching – that internally/externally or both (as it relates to sati) is perhaps a refutation as well as a point of practice.
