यस्य ब्रह्म च क्षत्रं च उभे भवत ओदनः । मृत्युर्यस्योपसेचनं क इत्था वेद यत्र सः ॥ इति काठकोपनिषदि प्रथमाध्याये द्वितीया वल्ली ॥

ॐ

English Translation

Who, then, knows where He is-He to whom Brahmins and kshattriyas are mere food and death itself a condiment? 

ॐ

English Commentary

As for him who is not of this description, the sruti says: Of whom Brahmins and Kshatriyas, though the stay of all virtue and the protectors of all, are the food; and Death, though destroyer of all, is only a pickle being insufficient as food. How can one of worldly intellect, devoid of helps above described, know where that âtman is, in this manner, as one who is furnished with the helps above described?
