This, all these Vedic scriptures, they are interrelated. They are not contradictory. If somebody says that "We find some contradiction from Vedic literature, from this literature to that literature," no. There is nothing at all, any contradiction, even, even in the preachings of the great ācāryas. I am speaking of India. There were many great ācāryas, I mean to say, reformers, came. Lord Buddha also appeared in India. Then, after Lord Buddha, Śaṅkarācārya came. Then, after Śaṅkarācārya, Śrī Rāmānujācārya came. Then, after Śrī Rāmānujācārya, Madhvācārya, and then, lately, Śrī Caitanya, Lord Caitanya. He came. But you will find a link, a link, although superficially we may see that Lord Buddha is speaking something which is contradictory to Lord Śaṅkarācārya's teaching, or Rāmānujācārya is speaking something which is contradiction to Śaṅkara. No. There is no contradiction. It is the question of studying how they are paving way for ultimate spiritual realization. That requires a very, I mean to say, substantial knowledge, how they are paving the way, just step by step.
Just like Lord Buddha's teaching. Lord Buddha's teachings is... That is also detachment from matter, nirvāṇa. Nirvāṇa. But he does not speak anything about the spirit soul. Because the position in which he was speaking, that position, for the human, humanity, was not suitable for understanding what is the constitution of spirit, therefore he did not say anything about spirit. He simply preached nonviolence. So far our body is concerned, he stressed on the point that we should be nonviolent. We should not be killing animals anymore. That was his preaching. Similarly, Śaṅkara... A little more than Buddha. He said, "No, no. Matter is not all. The spirit is real thing. Matter is false." Brahma satyaṁ jagan mithyā. Now, he did not say about the activities of spiritual life. He simply gave hint that there, that matter is false. Matter is generated by spirit. Spirit is the real, principle thing. Just like Buddha did not say anything about spirit. He simply wanted that detachment of, from matter. But detachment from matter... Then where is my stand? Where is my stand? If I leave this room, I must have another room to stay. So that is the position of Buddha. He did not say about the spirit. But Śaṅkara, Śaṅkara said, "No, matter is our false position. Spirit is real position." But he did not say anything, what are the activities of the spiritual life. Then Śrī Rāmānujācārya came. He described the actual position of spiritual life. These are gradual development. Your, I mean to say, Lord Jesus, also, Lord Jesus Christ, he also gave hints of spiritual life, kingdom of God. So when we speak of kingdom of God, a kingdom, vacant, cannot be. Kingdom means there must be activities. Otherwise, what is the meaning of kingdom? So, of course, he did not give any detailed account of the kingdom of God, but he gave hint.
So these are gradual development so far the human society is concerned. As the position is. The whole process is, as Lord Śrī Kṛṣṇa says in this Bhagavad-gītā,
- yadā yadā hi dharmasya
- glānir bhavati bhārata
- abhyutthānam adharmasya
- tadātmānaṁ sṛjāmy aham
- (BG 4.7)
The whole material atmosphere is going on, but we... There is a program. There is a plan. The plan is that, as soon as the living entity is promoted by gradual evolution, promoted to the platform of human life, he has to understand his spiritual position. That is the whole program.
