"If you pour water on the root of the tree, the water reaches to the branches, to the twigs, to the leaves, to the flowers, to the fruits automatically. You simply pour water on the root. That is the system. If you pour water on the every leaf, I think you'll have no time. 'Oh, there are millions of leaves. How we can…?' No. Take the root and pour water and it will reach. That is the way. Similarly, if you love your society, your friends, your country, your family, yourself, your dog, everything — if you love Krishna, all love will be distributed. But if you don't love Krishna, if you simply love this, simply love that, simply that, it will be never be perfect.
Therefore the whole world is confused. They do not know where to repose the love. That do not know. Therefore Krishna is canvassing: sarva-dharmān parityajya mām ekam (BG 18.66). 'Come here! Love Me! Increase your attachment for Me. Everything will be all right.' Otherwise it is simply vague. Śrama eva hi kevalam. Simply waste of time."

"So this Krishna consciousness is a science. You have to take it scientifically, as they are described in the authoritative books, and test it by your reason and argument and knowledge, and follow it. It is science. It is not sentiment. Whatever we are doing here, the dancing, singing and everything, that is all scientific. Simply you have to understand it. Therefore jñānī, only a person who is in knowledge, who is in knowledge of the science of Krishna, he can make an rapid advancement, and he is very dear to Krishna. Because slow but sure, he is making sure progress. It is no sentiment. So jñānī. Priyo hi jñāninaḥ atyartham. Atyartham means very… Aham. Krishna is very dear to the person in knowledge, and that man is also very dear to Krishna. Reciprocal. If you love Krishna, then Krishna will love more than you. You can… What capacity you have got to love Krishna? But Krishna will love. He has got immense capacity. So that is a science."

"You love Krishna, and Krishna loves you. Krishna loves you, even without your love. Otherwise, how you are eating? You cannot live even for a moment without Krishna's mercy. That's a fact. Eko bahūnāṁ yo vidadhāti kāmān."

"We should not love Krishna for some material gain. It is not that 'Krishna, give us our daily bread, then I love You. Krishna, give me this, then I love You.' There is no such mercantile exchange. That is wanted. Krishna wants that kind of love."

"Actual love is possible with Krishna. That is actual love. Once you love Krishna, it cannot be broken at any time. It cannot be broken, any, any circumstances. So therefore somehow or other we have to… Yena tena prakāreṇa manaḥ kṛṣṇe niveśayet (Bhakti-rasāmṛta-sindhu 1.2.4). Somehow or other you just engage yourself in loving Krishna. That is the success of life."

"Outside devotees, the devotees who are outside Vṛndāvana, they are studying the inhabitants of the Vṛndāvana, how great they are. But the inhabitants of Vṛndāvana, they don't care to know how great is Krishna. That is the difference. So our business is simply to love Krishna. The more you love Krishna, the more you become perfect. It is not that it is necessary to understand Krishna, how He has created. The things are mentioned there. Krishna is explaining Himself in the Bhagavad-gīta so much. Don't bother very much to know Krishna. That is not possible. Simply increase your unalloyed love for Krishna. That is perfection of life."
