Devotee (4): We cannot see Kṛṣṇa, because our eyes are impure . . .
Prabhupāda: Then you are following blindly.
Devotee (4): But by following the scriptures and the śāstras we get pure.
Prabhupāda: Yes. Feeling. That is anubhava. Anubhava ananta svarupa, parameśvara. That is the and then . . . (indistinct) . . . you can feel His presence. That is being explained here (reads Sanskrit commentary)
This very simple. Prahlāda Mahārāja saying that as the expert gold miner, when he sees there are gold particles in the field, naturally he concludes . . . still, in India there is a river, in that river gold particles, in the water gold particles can be found. Gold particles. Many poor men, they whole day work and strain the water in different way and get some little gold, still.
So, by the symptoms, by the symptoms the expert gold miner finds out that, "Here is gold, gold mine." Because in the within the soil, or with the soil you find some gold particles. That is the way, here it is said. Similarly, one can find out Kṛṣṇa by the symptom, the characteristics, of this world.
There are common sense. Just in everything there is a controller, there is a life. Just like in my body, I am controlling this body, and there is living force, living symptoms. Similarly, this whole world which is going on, there are so many things that are that is . . . that requires nice brain. This planetary system is moving nicely, exactly to the order. So one should consider that there must be some brain behind this—how things are going so nicely. That is common sense.
