"The sages, knowing Me as the ultimate purpose of all sacrifices and austerities, the Supreme Lord of all planets and demigods and the benefactor and well-wisher of all living entities, attain peace from the pangs of material miseries."
"Everything is enacted by the laws of nature, and these laws are under the direction of the Supreme Personality of Godhead. The atheists, or unintelligent men, do not know this. They are busy making their own plans, and big nations are busy expanding their empires. And yet we know that in due course of time many empires have come into existence and been destroyed. Many aristocratic families were created by people in their extreme madness, but we can see that in the course of time those families and empires have all been destroyed. But still the foolish atheists do not accept the supreme authority of the Lord. Such foolish people unnecessarily concoct their own duties without referring to the supreme authority of the Lord. The so-called political leaders are busy making plans to advance the material prosperity of their nation, but factually these political leaders only want an exalted position for themselves. Due to their greed for material position, they falsely present themselves as leaders before the people and collect their votes, although they are completely under the grip of the laws of material nature. These are some of the faults of modern civilization. Without taking to God consciousness and accepting the authority of the Lord, the living entities become ultimately confused and frustrated in their planmaking attempts. Due to their unauthorized plans for economic development, the price of commodities is rising daily all over the world, so much so that is has become difficult for the poorer classes, and they are suffering the consequences. And due to lack of Kṛṣṇa consciousness, people are being fooled by so-called leaders and planmakers. Consequently, the sufferings of the people are increasing. According to the laws of nature, which are backed by the Lord, nothing can be permanent within this material world; therefore everyone should be allowed to take shelter of the Absolute in order to be saved. In this regard, Lord Kṛṣṇa says in Bhagavad-gītā (BG 5.29):
jñātvā māṁ śāntim ṛcchati
'The sages, knowing Me as the ultimate purpose of all sacrifices and austerities, the Supreme Lord of all planets and demigods and the benefactor and well-wisher of all living entities, attains peace from the pangs of material miseries.'
If one wants peace of mind and tranquillity in society, he must accept the fact that the real enjoyer is the Supreme Personality of Godhead. The Lord is the proprietor of everything all over the universe, and He is the supreme friend of all living entities as well. By understanding this, people can become happy and peaceful individually and collectively."
(Śrīmad-Bhāgavatam 4.24.66, Purport)
"Great personalities of the material world are very eager to render welfare service to human society, but actually no one can render better service than one who distributes the knowledge of spiritual realization in relation with the Supreme Personality of Godhead. All living entities are within the clutches of the illusory energy. Forgetting their real identity, they hover in material existence, transmigrating from one body to another in search of a peaceful life. Since these living entities have very little knowledge of self-realization, they are not getting any relief, although they are very anxious to attain peace of mind and some substantial happiness. Saintly persons like the Kumāras, Nārada, Prahlāda, Janaka, Śukadeva Gosvāmī and Kapiladeva, as well as the followers of such authorities as the Vaiṣṇava ācāryas and their servants, can render a valuable service to humanity by disseminating knowledge of the relationship between the Supreme Personality of Godhead and the living entity. Such knowledge is the perfect benediction for humanity. Knowledge of Kṛṣṇa is such a great gift that it is impossible to repay the benefactor."
(Śrīmad-Bhāgavatam 4.22.47, Purport)
"Devotional service means attaining peace from all disturbances caused by material contamination. In other words, it is the process by which the mind is cooled. The mind can be peaceful and thoroughly cleansed when one no longer desires anything but devotional service."
(Caitanya-caritāmṛta Madhya 12.135, Purport)
Devotee: "A faithful man who is absorbed in transcendental knowledge and who subdues his senses quickly attains the supreme spiritual peace."
Prabhupāda: Yes. So a faithful man who understands that, "I am part and parcel of Kṛṣṇa," and he is always engaged in the service of Kṛṣṇa in Kṛṣṇa consciousness, who is absorbed in transcendental knowledge—this is samādhi, absorbed—and who subdues his senses quickly... Subdue means if you apply your senses in the service of Kṛṣṇa, then your senses are subdued automatically.
Just like if you make your promise that "I shall take only kṛṣṇa-prasādam," then your nonsense eating or satisfying the tongue by nonsense eating—immediately stopped. That is subduing. God does not say that, "You starve." God does not say. Or "You do not eat nice things." But God says: "You eat really nice things; don't eat nonsense nice thing." Instead of eating nonsense meat, you eat sweet balls. You see? It is not stoppage, but giving better.
So better food, better consciousness, better knowledge, better life, better association—what do you want more? Better philosophy. What do you want more? Naturally "Attains the supreme spiritual peace." His everything is better; there must be... the result must be the better, the supreme peace.

"Everyone is hankering after peace, but this is the way of attaining peace: to revive your relationship with Kṛṣṇa, to engage your mind fully in the service of Kṛṣṇa, in the matter of understanding Kṛṣṇa. And if you understand Kṛṣṇa... The books are there. Bhagavad-gītā is there. Śrīmad-Bhāgavata is there. You have got your reason. You have got your knowledge. Try to understand Kṛṣṇa. Then your life is successful."
(Srila Prabhupada Lecture, Bombay, January 18, 1975)
"Mr. John Lennon is anxious for peace in the world, so also is everyone anxious for peace in the world, but it should be known how that peace can be attained. If we keep the human society as it is, there is no possibility of peace. It is not a question of simply accepting God as the center of everything and peace will be achieved, but the question is how to live in God. Mr. Lennon wants to stop war, but the war is the creation of different politicians. So unless on the summit of administration there are actually Krishna Conscious men, we cannot stop war. Therefore people in general must understand the importance of Krishna Consciousness, and they must in this democratic day send their real representatives who can make right decisions whether there should be war or no war. We find from the history of Mahabharat that the battle of Kurukshetra was because of the belligerent attitude of Duryadhana. So such war as is was conducted under the advice of Lord Krishna is not bad, but war declared and executed by demonic politicians is certainly very bad. A Krishna conscious person like Arjuna is not inclined to the activities of warfare, but when there is a necessity for peace in the world to educate men to become Krishna Conscious, a Krishna Conscious person does not lag behind. Therefore the first necessity for peace in the world is to instruct men how to become Krishna Conscious, because as soon as one becomes Krishna Conscious all the good qualities in human society are manifested. So if it is possible that the party of Mr. Lennon and Mr. Harrison cooperate with this Krishna Consciousness Movement, I am sure we shall be able to stop all this nonsensical war."
(Srila Prabhupada Letter, June 12, 1969)
"The final conclusion in the Bhagavad-gītā is that if you want to be peaceful, if you want the peace of your mind, you should understand three things. That three things are that to understand that God is the supreme enjoyer. This is one. He is the proprietor of everything, and He is friend of everyone. If you learn these three things only, very scientifically, that God is the proprietor, God is the enjoyer and God is the supreme friend of everyone, then your life is successful. And these simple things will be understood by you by chanting God's name: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare."
