If you do not give service to Kṛṣṇa, then you must know you are simply spoiling your energy. That's all. Because this service will never give you satisfaction; neither to the served. The same example I have given: Gandhi also, on the very day he was shot down, in the morning he said to his secretary, "Oh, I am so much disgusted. I do not like to deal with it." That was published in the paper. That means he was disgusted, and his countrymen also became disgusted, so that he shot him down. This world is like that. You give service to somebody—he is not satisfied; you are not satisfied. Frustrated. So ask your any family member, your wife or your children or any friend, so "I have given you so much service. Are you satisfied?" "Oh, what you have given?" (laughter) You have to do so many things. You have got so much things. And no. So this is the world, like that.
But our tendency is to give service. But because we are not giving service to God, Kṛṣṇa, we are frustrated. This is rāja-vidyā. This is the king of education. Pratyakṣā . . . su-sukhaṁ. And if you give service to Kṛṣṇa, you give service to everyone. It is so nice thing. Su-sukhaṁ. Just like if you pour water on the root, then you water the leaves. There are many millions of leaves in the tree, millions of twigs. But this process will satisfy everyone.
