त्वमक्षरं परमं वेदितव्यं
त्वमस्य विश्वस्य परं निधानम्।
सनातनस्त्वं पुरुषो मतो मे।।11.18।।
11.18 You are the Immutable, the supreme One to be known; You are the most perfect repository of this Universe. You are the Imperishable, the Protector of the ever-existing religion; You are the eternal Person. This is my belief.
11.18 You alone are the Supreme Imperishable Person indicated as that which ought to be realised in such Upanisadic passages as: Two sciences are to be known (Mun. U., 1.1.4). You alone are the Supreme Substratum of the universe, i.e., supreme support of this universe. You are immutable, namely, not liable to mutation. Whatever might be your attributes and divine manifestations, You remain unchanged in Your form. You alone are the guardian of the eternal law - You who protect the eternal Dharma of the Veda by incarnations like this. I know you are the everlasting Person. I know You are the eternal Person, described in such passages as, I know this great Purusa (Tai. A., 3.12.7) and Person who is higher than the high (Mun. U., 3.2.8). You, who were till now known to me as the most distinguished of the race of Yadu, have been realised by me now through direct perception as of this nature, i.e., of a nature unknown to me before. Such is the meaning.
