So servant class... A brahmacārī living at the care of spiritual master, he is advised that "You shall carry out the orders of your spiritual master nīcavat, just like the śūdra class." Because a person coming to spiritual master, they are coming from brāhmaṇa family or kṣatriya family or high caste family. But he may say, "Oh, I am coming from a brāhmaṇa family, and my spiritual master is ordering to brush his shoes? Oh, how can I do?" Therefore it is advised, nīcavat. When you are serving spiritual master, you should always think that "I am lowest of the animals." Nīcavat. In that condition you can simply inquire. Otherwise, you have no capacity. There is no need of wasting time, because he will not understand. He will unnecessarily... Praṇipāta.
Praṇipāta means surrender. So nobody wants to surrender, especially in this material world. Everyone thinks, "Oh, I am the lord. I am the monarch of all I survey. Why shall I surrender?" Independent. Especially in the Western countries. They are refusing to surrender to the social laws, to the king's law, everything. But here is the process: surrender. Surrender means everyone is puffed up with some so-called knowledge, and he thinks that "I am perfectly all right. My knowledge is perfect. Why shall I surrender?" But if you want to receive knowledge actually from the person who has actually knowledge, then you must surrender there. This is the process. Just like Vyāsadeva first of all: paraṁ satyaṁ dhīmahi. This is surrender. Surrender. Without surrender, we cannot get knowledge. And in another... There are many places. Jñāne prayāsam udapāsya namanta eva. To understand God, Brahmā says, jñāne prayāsam udapāsya. Leaving, giving up this nonsense habit of speculation, "God is like this, God is like that," prayāsam, jñāne prayāsam... The jñānīs, they are discriminating, "No, this is not God." The scientists, they will say, "This is the fact." And then, one year after, "No, this is not fact. Now we have improved, another." And again, three years after, they will say another. There is no standard knowledge. What is the final knowledge, they do not know. Therefore these kind of speculative habits or scientific research is simply waste of time. They cannot understand what is the ultimate truth.
