teacher is best,' and hence considering it advisable that the teacher himself should instruct Upakosala as to the attributes of the highest Brahman, the place with which it is to be connected in meditation and the way leading to it, they tell him 'the teacher will tell you the way,' the 'way' connoting everything that remains to be taught by the teacher. In agreement herewith the teacher--having first said, 'I will tell you this; and as water does not cling to a lotus leaf, so no evil clings to one who knows it'--instructs him about Brahman as possessing certain auspicious attributes, and to be meditated upon as abiding within the eye, and about the way leading to Brahman.--It is thus a settled conclusion that the text under discussion refers to that Brahman which was introduced in the passage 'Ka is Brahman,' and that hence the Person abiding within the eye is the highest Self. But--an objection is raised--how do you know that the passage 'Ka (pleasure) is Brahman, Kha (ether) is Brahman' really refers to the highest Brahman, so as to be able to interpret on that basis the text about the Person within the eye? It is a more obvious interpretation to take the passage about Ka and Kha as enjoining a meditation on Brahman viewed under the form of elemental ether and of ordinary worldly pleasure. This interpretation would, moreover, be in agreement with other similarly worded texts (which are generally understood to enjoin meditation on Brahman in a definite form), such as 'Name is Brahman', 'Mind is Brahman.' 16. For that very reason that (ether) is Brahman.
