संघातोऽपि तथा नाहमिति दृश्यविलक्षणम् ।द्रष्टारमनुमानेन निपुणं सम्प्रधारय ॥ १७ ॥
In plain words
The whole bundle — body, senses, mind taken together — is not "I" either. Reason it through carefully and settle it: the Seer is of an altogether different order than anything seen.
Close to the Sanskrit
The aggregate too, likewise — 'not I' — thus; the Seer, distinct from the seen, ascertain skilfully by inference.
