What is the Greatest form of love?

self-realization ; ) the values of this culture have shifted us away from what we really are. so i think it takes stripping away what we are not to find what we truly are which is boundless love and freedom. i think the greatest form of love already exists inside of everyone. coming to this place through "self-realization" and hate to call it, but "meditation" is a process that i think will give birth to "the greatest forms of love" in the sense that i think you are asking about. therefore i guess i would have to think that the greatest form of love can be felt, expressed, and experienced without having to take much form except through our bodies. just looking at another person in silence without having to have words, action, or anything else can be an expression of this "greatest form of love". True love doesn't have to be sacrificed for because i think true love is eternal it never began and will never end so why would someone need to sacrifice for it. i think sacrifice is just a concept made up by the mind for maybe a egotistical "form" as noble, good hearted, and well intentioned as it may be.
