So the conclusion should be that sanātana-dharma means that the living entity is eternal, he must seek out his eternal service. That is called sanātana-dharma. Sanātana-dharma does not mean that having a great big tuft, and tilaka, or dressing in a certain manner, or... Then everything are changing. That is not sanātana-dharma. Whatever is changeable, that is not sanātana-dharma. Sanātana, try to understand sanātana. Sanātana means eternal, and the living entity, being eternal, he must have some eternal engagement. That is called sanātana-dharma. Here, in the Bhagavad-gītā, the word sanātana has come in many places. In one place, Second Chapter, twenty-fourth verse, it is said,
- acchedyo 'yam adāhyo 'yam
- akledya aśoṣya eva ca
- nityaḥ sarva-gataḥ sthāṇur
- acalo 'yaṁ sanātanaḥ
Nitya, nityaḥ sarva-gataḥ sthāṇur acalo 'yaṁ sanātanaḥ. There are many other symptoms of the living entity. They are described in the Bhagavad-gītā very nicely, positively and negatively. In some of the verses, the definition is being given in negation: "It is not this." Because with our blunt material eyes, we cannot find out where is the soul in this body; therefore Kṛṣṇa is describing the characteristic of the soul in a negative way in several verses. And you know that sometimes it is required, according to logic, that definition by negation: "It is not this." I cannot express for the time being a thing, what it is, but I can distinguish what it is not. So similarly, at the present moment, everyone is under ignorance. He does not know what is the soul. That is the basic principle of missing point of this material civilization. I talked with many big, big professors in Europe. Most of them, they do not know what is the soul. (aside:) That sound cannot be stopped for the time being? When I was in Moscow, I had the opportunity of talking with some professors. One of them was very interested, Professor Kotovsky. So he said, "Swamijī, after death everything is finished." So I was simply surprised that a responsible professor, teaching staff, he's completely in ignorance about the existence of soul. So that is the defect of the modern civilization. One who is not perfect in knowledge, he is as a teacher, he's passing on as a teacher. Andhā yathāndair upanīyamānās te 'pīśa-tantryām uru-dāmni baddhāḥ. Andhāḥ means blind. One blind man, he is trying to help other blind man. So what is the use of such advancement of education? If the teacher himself is blind, then what is the use of taking knowledge from him? That is going on.
