There are different varieties of living entities, 8,400,000 varieties. How many you have seen? Therefore you have to take knowledge from the perfect source. Then we you can understand. Tad-vijñānārthaṁ gurum eva abhigacchet. This is Vedic injunction. If you want to know perfectly everything, then you must go to the proper teacher. Then you will learn. But how you can imagine from here? A dwarf is trying to touch the moon. How it is possible? That is not possible. The Vedic injunction is in order to... Tad-vijñānārtham. Higher science. Vijñāna means science. If you want to know higher science—not this science, simply filling of the belly, not this science—higher science, which is above fulfilling the belly, that, for that purpose, you have to go to guru. Guru means who knows more than you. That is guru. So who can know more than Kṛṣṇa? Therefore we have to accept Kṛṣṇa as guru and learn from Him. Then you'll get perfect knowledge.

“Indeed, we are like a dwarf who wants to capture the moon. Although we are completely unfit, a desire to receive Your mercy is awakening within our minds.
The son said, "Oh, you are most degraded! You want to marry my sister, just like a dwarf who wants to catch the moon!"
“Like a dwarf who wants to catch the moon, I have tried my best many times, but I have never been successful.
One who wants to describe the transformations of ecstatic love of Kṛṣṇa is like a dwarf trying to catch the moon in the sky.

The scope and implications of this task are breathtaking, and I am feeling very small and insignificant in confrontation with it, just like a dwarf trying to touch the moon. However, if you want me to perform this task, then kindly give me your mercy and bless me..."
Prabhupāda: Yes. You train up assistants and this will be recognized by government and everyone. You'll do more than Columbus. (laughter) In the Washington, in different compartments, a different explanation of Bhāgavata śloka by dolls will attract millions of people to see. Will it not?
