Everyone is hankering after santi [peace]. The santi formula is given everywhere in the sastra. And the Supreme Personality of Godhead, Krsna, is personally saying, "This is santi." What is this?
bhoktaram yajna-tapasam
sarva-loka-mahesvaram
suhrdam sarva-bhutanam
jnatva mam santim rcchati
 [Bg. 5.29]
Suhrdam sarva-bhutanam — who? Not these political leaders. We are taking these political leaders as our friend and carried away by their dictation. Some political leader says, "You do like this," another political leader, "Do like that." If we want to take advice of real well-wisher, so suhrdam sarva-bhutanam. Similarly, a sadhu, he is also suhrdam sarva-dehinam, the same thing. As Krsna is the supreme friend, well-wisher, suhrt… Suhrt means good heart. Friend, mitra, it is little different from suhrt. Mitra means I make friendship with you with some motive. But a father, he is suhrt, mother is suhrt, always well-wishing. Or there may be some friend also, always well-wishing. But the best example, that the father is always well-wishing: "How my son will be well situated? How he will be happy?" Similarly, Krsna is… Krsna says that "When one can understand Me as suhrdam sarva-bhutanam," then santim rcchati, "then he will get santi, santatvam." When we accept it, firmly convinced that "Krsna is my father, Krsna is my friend, Krsna is my well-wisher…" And Krsna says. Where is the difficulty? Aham tvam sarva-papebhyo moksayisyami [Bg. 18.66]. He takes charge. Kaunteya pratijanihi na me bhaktah pranasyati [Bg. 9.31]. He is giving assurance.
mam hi partha vyapasritya
ye 'pi syuh papa-yonayah
striyo vaisyas tatha sudras
te 'pi yanti param gatim
 [Bg. 9.32]
Everything is there. So on account of this dirty position of material contamination, we cannot accept Krsna as the real friend. Therefore we cannot get santi. So if we want really santi, then we must accept the formula, suhrdam sarva-dehinam jnatva mam, not this political leader, that political leader, no. They do not know what is the actually path of santi. They cannot. They do not have santi in themselves. How they can…? "Physician heal thyself." The physician himself is a diseased person, maya-mohita, so how they can help us? So this is not possible. We have to accept Krsna as suhrdam sarva-bhutanam jnatva: [Bg. 5.29] He is the proprietor of everything. Sarva-loka-mahesvaram. Mahesvaram. Isvara, mahesvaram. Paramesvaram. Mahesvaram or paramesvaram. Isvarah paramah krsnah [Bs. 5.1]. In this way, if we can understand that "Krsna is the proprietor, Krsna is the enjoyer, Krsna is my supreme friend," then we can get santi.
