Guns are for killing people. Guns are necessary against foes. Guns are due to distrust and fear. Distrust and fear are from the self as well as the other, essentially from small selves: self-centeredness. Self-centeredness is the fundamental obstacle against unity.
Anyone who aspires to unity and peace must become selfless. Selflessness has no distrust and fear: great people have no foes. Friends need no guns. Friendship ensures unity. Friendship (from friendly love: philia-domos; beloved domain: priya-dhaman) knows no bounds, but limitless liberation, light, love, and life.
Actually selfishness, distrust and fear, foes and guns are intertwined, enforcing and expanding (self-sense, psychic-syndrome, social system, sales-symbiosis, etc.). They are in egg-chick relations. The solution is in the link, each one’s holistic vision and action wholly linking. “Man started it; man can stop it.”
The same applies to the relationship between peace and weapons. Anyone who aspires to and announces peace must stop selfishness, see the interdependence of all (self/other, here/there, now/then, mind/body, etc.), become great ones, true friends, and renounce weapons.
Anyone who aspires to limitless liberation, light, love, and life here and now must renounce small selves like bubbles, become holy (wholly wholesome: entirely wholesome with the entire world), like the great ocean. Religions (from reunion: religare) must reunite to holiness, without selfishness and sectarianism, for the benefit of all.
