By chanting and hearing, the dirty things within the heart will be cleansed. Then you will understand what is your position in relationship with God. You'll understand what is God. Therefore in this age especially, Kali-yuga, because people cannot perform any other austerities... They're unable. They're so dull. Mandāḥ sumanda-matayo manda-bhāgyā hy upadrutāḥ (SB 1.1.10). This is the position of the people of this age. Prāyeṇa alpa āyuṣaḥ. Generally, their span of life is very short. It is decreasing, day by day. As our forefathers lived ninety years, hundred years, now we are not living up to such extent of ages. Generally, people are dying... In India, the average age is thirty-five years. In other countries, maybe little more. But gradually it is decreasing, and it will decrease to such a point that even a, if a man lives for twenty to thirty years, then he'll be considered as grand old man. That, that day will come.
So this age... Therefore śāstra says, prāyeṇa alpa āyuṣaḥ. Generally, almost everyone is short-living. Prāyeṇa alpa āyuṣaḥ kalau asmin yuge janāḥ. Asmin yuge, kalau, they are very short-living. Then again, mandāḥ: all rascals. Mandāḥ, third class; no first-class men. Practically no brahminical qualification. All śūdra qualification.
