It seems that for some people the idea of compassion entails a complete disregard for or even a sacrifice of their own interests. This is not the case. In fact, you first of all have to have a wish to be happy yourself - if you don't love yourself like that, how can you love others?
You must love yourself before you love another. By accepting yourself and fully being what you are, your simple presence can make others happy You yourself, as much as anybody in the entire universe, deserve your love & affection.
Love yourself. Just love yourself. In fact, the love of the self cures every kind of problem you have with yourself. For instance, if someone calls you nappy-headed, it rolls right off your body, if you love nappy hair. Or if someone calls you buck-toothed or too black, that won't be a problem if you love being buck-toothed or black. If you love it, then so what. The development of self-love cures many of the ills that people suffer from.
By the experience of active love. Strive to love your neighbour actively and indefatigably. In as far as you advance in love you will grow surer of the reality of God and of the immortality of your soul. If you attain to perfect self-forgetfulness in the love of your neighbour, then you will believe without doubt, and no doubt can possibly enter your soul. This has been tried. This is certain.
You will have many enemies, but even your foes will love you. Life will bring you many misfortunes, but you will find your happiness in them, and will bless life and will make others bless it-which is what matters most.
