In all varieties of species of life . . . there are 8,400,000 species of life: the aquatics, the trees, the plants, the birds, the bees, the insects . . . then human being. And out of the human being also, there are so many uncivilized. Civilized human being are very few. And out of the civilized human being, very few take to religious life. Very few. And out of these so-called religious human society, most of them, they simply designate, "I am Hindu," "I am Muslim," "I am Christian," but they do not know about religion.
And one who knows about—not knows; little attracted—they are engaged in philanthropic work: to give help to the poor or to open a school, hospital. This is called karma-kāṇḍa. Out of many millions of these karma-kāṇḍa people, one is jñānī. Jñānī means "one who knows." And out of millions of persons who knows, one is liberated. And out of millions of liberated person, one can understand what is Kṛṣṇa. This is the position of Kṛṣṇa.

So to understand Kṛṣṇa is little difficult. Actually, to understand God is a subject matter very difficult. But the God Himself is explaining Himself in the Bhagavad-gītā: "I am thi . . . I am like this. I am like this. This material nature is like this. The spiritual nature is like this. The living entities are like . . ." Everything are completely described in the Bhagavad-gītā—God Himself, giving His own knowledge.
And that is the only process to understand God. Otherwise, by speculation we cannot understand God. It is not possible. He is unlimited and we are limited. Our knowledge, our perception, all of them are very limited. So how we can understand the unlimited? But if we accept the version of the unlimited, that "He is like this, like that," then we can understand. That is perfect knowledge.
