A brahmin should be truthful in any circumstances. He will never speak lie. Truthful, satya. Śama. Śama means keeping the mind always in equilibrium. And dama, dama means keeping the senses under control. Śama dama titikṣa. Titikṣa means toleration. There may be so many tribulations, but a brahmin is supposed to be very, very tolerant. Toleration.
The first-class example of toleration in the Western country: Lord Jesus Christ. He was being crucified; still, he did not take any steps. If he wanted, he could take steps, but he was tolerating. So this is the sign of brahminical symptom. Titikṣa ārjava. Ārjava means simplicity. A brahmin is not supposed to be crooked and duplicity. No. Simple.
It is said even the enemy wants to know something from him, he will clearly say: "It is this." That is called simplicity. Then jñānam. Jñānam means knowledge, full knowledge. And vijñānam means scientific knowledge, practical application in life. That is called vijñānam. Āstikyam. Āstikyam means to have full faith in Vedic literature. That is called āstikyam. These are the signs of brahmin.
So those who are going to be initiated with this sacred thread, they must always remember to follow all these rules and regulations. We should always remember that this Kṛṣṇa consciousness movement is meant for purifying the human society. Unless the human society is purified, there will be so many problems and disturbances in the human society.
At least a certain percentage of the human society must be brahmin, otherwise the society cannot make any progress in spiritual life. And if we cannot make progress in spiritual life, then our human life is frustrated. After 8,400,000 species of life, evolution, one gets this human form of life. And if he does not properly utilize it, then he is committing suicide.
