He says:-- Consider the sun.

Were it to say now, "I am the sun of yesterday," it would speak the truth.

And should it, bearing the sequence of time in mind, claim to be other than that sun, it still would speak the truth.

In like manner, if it be said that all the days are but one and the same, it is correct and true.

And if it be said, with respect to their particular names and designations, that they differ, that again is true.
