Prabhupāda: Arjuna is representing himself as a common man in the sense that he was not a mendicant or he has renounced his family life or he has no connection with his bread problem. Because he was on the warfield to fight for the kingdom. So he's supposed to be an ordinary man. So for ordinary men who are engaged in these worldly activities for earning livelihood, family life, children, wife, or so many problems, it is not practical.
That is the point here. It is practical for one who has already renounced everything completely—in a secluded sacred place, just like in the hill or in the cave of the hill, alone; no public disturbance. So where is the opportunity for ordinary man, for us, especially in this age?
Therefore this yoga system is not practical. It is admitted by Arjuna, who was a great warrior. And he was so advanced, he belonged to the royal family and very expert in so many things. He says that it is impractical. Just try to understand. And what we are in comparison to Arjuna? If we try this system, it is not possible. Failure is sure.
Go on reading the purport.
Revatīnandana: "The system of mysticism described by Lord Kṛṣṇa to Arjuna is here being rejected by Arjuna . . ."
Prabhupāda: Yes, rejected, Arjuna. Yes.
Revatīnandana: ". . . out of a feeling of inability. It is not possible for an ordinary man to leave home and go to a secluded place in the mountains or jungles to practice yoga in this Age of Kali. The present age is characterized by a bitter struggle for life of short duration."
Prabhupāda: Yes. First of all, our duration life is very short. If you study the statistics, you can see your forefathers who lived for hundred years or eighty years, ninety years. Now sixty years, seventy years people are dying. Gradually it will decrease. In this age the memory, the duration of life, mercifulness, so many things will decrease. That is the symptom of this age.
