'And I will declare to you one foot of Brahman.' 'Declare it, Sir,' he replied. He said to him; 'The eastern region is one quarter, the western region is one quarter, the southern region is one quarter, the northern region is one quarter. This is a foot of Brahman, consisting of the four quarters, and called Prakâsavat (endowed with splendour).'

In plain words: The bull offers to teach Satyakama one part of Brahman (the ultimate reality behind everything). It says the four directions, east, west, south and north, make up this part, which is called 'Full of Splendour.'
