Chandanācārya: Śrīla Prabhupāda, when someone is sick, he willingly goes to the doctor.
Prabhupāda: Yes.
Chandanācārya: So . . .
Prabhupāda: That is the injunction of the Vedas: tad-vijñānārthaṁ sa gurum eva . . . (MU 1.2.12). Therefore these rascals should go to a bona fide guru.
Chandanācārya: So how we can get them to willingly come . . .
Prabhupāda: Ah?
Chandanācārya: . . . to the guru?
Prabhupāda: No. Just like if you are diseased, you are suffering the pains, so naturally you shall be inclined how to reduce the pain, how to get out of this pain.
Chandanācārya: But the scientists . . .
Prabhupāda: But these rascals, even though are suffering three kinds of pains, tri-tāpa-yatna . . . just like why you are covered? Because there is pain, severe cold; similarly severe heat. So we are suffering, either in summer season or winter season. We are suffering, tri-tāpa-yantraṇā. There is suffering from our mind, from our body—this is natural suffering. There is bodily suffering, mental suffering, then suffering caused by other living entities. So we are always suffering. But still they're thinking that, "We are happy." The disease is already there. Ah?
Just like the Arabian do not want to give you petrol. That means the suffering caused by other nations. So this is going on. They're simply trying to settle up. But the suffering's there. But they're not in their knowledge, that in spite of our all endeavors, the sufferings are there. What is the cause? Then whom shall I go to ask why the suffering is there? Tad-vijñānārthaṁ sa gurum (MU 1.2.12). Therefore you must approach to a person who knows how the suffering should be mitigated.
