Agape love in its purest form is the love for people. As they are. The Godly, accepting kind love that let's people be, who they are, the way they are, with no judgment, expectations, wants, needs, demands...
It's unconditional love that is programmed into every human being, but often being confused with unmet needs. Loving another human being, purely, means you want the best for them, you want them to be happy, regardless of you and your existence in their life.
It's the highest form of love, often unattainable by humans. As we are thinking and feeling creatures, with ego in our way.
