“The attraction is strong, because both men literally laid down their lives for their brothers. "Greater love hath no man than this." "Let me say, at the risk of seeming ridiculous, that the true revolutionary is guided by great feelings of love." Che Guevara wrote this,”

Excerpts from the two paragraphs above have sometimes been quoted in abbreviated form: At the risk of seeming ridiculous, let me say that the true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality... We must strive every day so that this love of living humanity will be transformed into actual deeds, into acts that serve as examples, as a moving force.

Context: At the risk of seeming ridiculous, let me say that the true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality. Perhaps it is one of the great dramas of the leader that he or she must combine a passionate spirit with a cold intelligence and make painful decisions without flinching. Our vanguard revolutionaries must idealize this love of the people, of the most sacred causes, and make it one and indivisible. They cannot descend, with small doses of daily affection, to the level where ordinary people put their love into practice.
The leaders of the revolution have children just beginning to talk, who are not learning to call their fathers by name; wives, from whom they have to be separated as part of the general sacrifice of their lives to bring the revolution to its fulfilment; the circle of their friends is limited strictly to the number of fellow revolutionists. There is no life outside of the revolution.
In these circumstances one must have a great deal of humanity and a strong sense of justice and truth in order not to fall into extreme dogmatism and cold scholasticism, into isolation from the masses. We must strive every day so that this love of living humanity will be transformed into actual deeds, into acts that serve as examples, as a moving force.

Context: It is not uncommon to charge slaves with great treachery toward each other, but I must say I never loved, esteemed, or confided in men more than I did in these. They were as true as steel, and no band of brothers could be more loving. There were no mean advantages taken of each other, as is sometimes the case where slaves are situated as we were, no tattling, no giving each other bad names to Mr. Freeland, and no elevating one at the expense of the other. We never undertook to do any thing of any importance which was likely to affect each other, without mutual consultation. We were generally a unit, and moved together. Thoughts and sentiments were exchanged between us which might well be called incendiary had they been known by our masters.

Context: Nothing can be greater than love. God is great only because He has infinite Love. If we want to define God, we can define Him in millions of ways, but I wish to say that no definition of God can be as adequate as the definition of God as all Love. When we say "God", if fear comes into our mind, then we are millions and billions of miles away from Him. When we repeat the name of God, if love comes to the fore, then our prayer, our concentration, our meditation, our contemplation are genuine.
