Pradyumna: "Foreseeing the incompetencies of the people in this age of Kali, or the iron age of quarrel, the sages requested that Suta Gosvāmī give a summary of all revealed scriptures, because the people of this age are condemned in every respect."
Prabhupāda: But the directions should be taken from scriptures. But there are many scriptures. So ācārya means, just like Gosvāmīs, they would read all the scriptures and take the essence of it and give it to his disciple that, "You act like this." Because he knows what to give, how to manipulate, so that his ekāntataḥ śreyas will be achieved. Ultimate goal. Therefore the ācārya knows how to adjust things, at the same time keep pace with the spiritual injunction. That is ācārya. It is not that the same thing to be applied everywhere. He is eager to engage actually the people in the real benefit of life, but the means may be different.
Just like my Guru Mahārāja. He is the first time that he allowed the sannyāsīs to drive in a motorcar. A sannyāsī never drives in a motorcar, you see? But not for sense gratification. Suppose we are going by aeroplane. The sannyāsī should walk. The Jain sannyāsīs, they never ride on a car, you know that. You know that. They will never ride on a car. But now they are also riding. But suppose we are preaching now. I came from India. If I would say: "I am sannyāsī. I will not ride in a car or aeroplane; I must walk," then what kind of preaching would have been? You see? So therefore it depends on the ācārya how to adjust things. So my Guru Mahārāja said: "All right, go on preaching on a motorcar. It doesn't matter."
These Gosvāmīs, they went to Vṛndāvana, severest type of austerity. They used to live underneath a tree. Now if in this age I advise you that you also live underneath a tree, then it will be difficult to preach. You see? Nobody is accustomed in that way, such severe type of austerity. They must be given, as far as possible, comfortable accommodation; otherwise they will not come. They will not take. Now this . . . this is the adjustment. The ācārya knows how to adjust things. The real purpose is how one will take to spiritual consciousness, or Kṛṣṇa consciousness. Keeping one's aim to that point, some concession may be given. As far as possible, keeping pace with the time, circumstances.
