In order to see first we have to purify the senses
So all our senses are imperfect. By imperfect senses, you cannot see the spirit soul. You cannot see even the spirit soul. How you can see the Supreme Soul, God? That is not possible. You have to purify your senses. Then you can see. Atah sri-krsna-namadi na bhaved grahyam indriyaih [Brs. 1.2.234]. The present blunt senses, material senses, all are imperfect. Even we hear the Lord's name, namadi, atah sri-krsna-namadi… Just like we are chanting. One who is spiritually advanced, he's enjoying this Hare Krsna, Krsna's name. But those who are blunt, they will see, they will think, "What these people are chanting?" Because he has no power to hear. Atah sri-krsna-namadi. But realization of Sri Krsna begins by hearing. That is the method. Sravanam kirtanam visnoh [SB 7.5.23]. If you hear about Krsna, if you chant about Krsna, then gradually, your heart will be cleansed. Ceto-darpana-marjanam bhava-maha-davagni-nirvapanam [Cc. Antya 20.12]. 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. Mandah sumanda-matayo manda-bhagya hy upadrutah [SB 1.1.10]. This is the position of the people of this age. Prayena alpa ayusah. 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.
