Śyāmasundara: But he says that there are two types of truth. There's innate truth...
Prabhupāda: This is innate truth: as three angles of a triangle are equal to 180 degrees, similarly snow is white. Snow is white, water is liquid, stone is hard, chili is hot, sugar is sweet. These are eternal truths, fundamental truths. Similarly, a living entity is eternal servant of God. This is eternal truth. It cannot be changed. Water is liquid. That is the natural position, but when water becomes hard, it is due to temperature, under certain conditions, but as soon as the temperature reduces, the water becomes liquid. So liquidity of water is truth. Similarly, whiteness of snow is truth. Similarly, servitude of the living entity is truth. But he is serving māyā. That is untruth. If we take that there are two types of truth, there cannot be two kinds of truth. Truth is one. What we take as truth, that is māyā.
Śyāmasundara: Oh, there's only one truth.
Prabhupāda: Yes. There can't be two truths.
Śyāmasundara: But due to our imperfect senses...
Prabhupāda: Yes. That is what is called māyā. Māyā has no existence, but it appears like truth. The same example: the shadow has no existence, but it also looks like my finger, and everything exactly. In the mirror you see your face exactly the same, but it is untruth. The truth is one. Truth cannot be two types of truth. What is taken as truth for the present moment, and by experience he comes to the right truth, that is called māyā.
Śyāmasundara: He says that these two types of truth are governed by two different principles: the truth of reason or the logically necessary proof, like the triangle...
Prabhupāda: This is reason, that truth is one. When we find another competitor truth, that is māyā. Truth cannot be two.
Śyāmasundara: This is what he says, that these innate truths are governed by the principle of contradiction. That is, the opposite of the truth is impossible to conceive. If something is true, the opposite of that truth is impossible to conceive.
Prabhupāda: The opposite is māyā. Opposite to truth is māyā.
