c5.s4.17

In the refrain of the first nine verses of RV. 10, 121 the supreme god is referred to as unknown by the interrogative pronoun *Ka*, Who? The answer given in the tenth verse, is that Prajāpati alone embraces all beings. This later led to the employment of *Ka* not only as an epithet of Prajāpati (AB. 3, 22⁷), but as a name, used by itself, of the supreme god (MS. 3, 12⁵). In the TS. (1, 7, 6⁶) Ka is expressly identified with Prajāpati⁷.
