Katha-1-2-14-anyatra

Sri Shankara’s Commentary (Bhashya) translated by S. Sitarama Sastri

If I am worthy, and you are, Oh Baghavan, pleased with me: other than virture, i.e., different from the performance of acts enjoined by the Sâstras, their fruits and their requisites and similarly from vice; other than what is made, i.e., effect; and what is not made, i.e., cause; and again other than the past, i.e., time gone by; and the future, i.e., time yet to come; and similarly the present, i.e., what is not conditioned by time (past, present and future); if you see or know anything like this, beyond the reach of all wordly experience, tell me that.
