नाहं भूतगणो देहो नाहं चाक्षगणस्तथा ।एतद्विलक्षणः कश्चिद्विचारः सोऽयमीदृशः ॥ १३ ॥
In plain words
I am not this body, this gathering of elements. I am not the senses either. I am some other thing entirely, unlike any of it. That is vicāra — and this is exactly what it looks like.
Close to the Sanskrit
I am not the body, the collection of elements; nor am I, likewise, the collection of sense organs. Something distinct from these [am I] — that inquiry, this one, is of such a kind.
