The System of the Vedanta according to Badarayana's Brahma-Sutras and Cankara's Commentary c2.4

c2.4

And now, in this our day, when the ancient waters are somewhat clogged by time, and their old courses hidden and choked, you come as the Restorer, tracing the old, holy streams, clearing the reservoir, making the primal waters of life potable for our own people and our own day; making them easier of access also, and this is near to both our hearts, for the children's children of those who first heard Çañkara, in the sacred land where he lived his luminous days.
