The highest and most radical type of love according to the Greeks is agape, or selfless unconditional love.
Agape is what some call spiritual love. It is an unconditional love, bigger than ourselves, a boundless compassion, an infinite empathy. It is what the Buddhists describe as “mettā” or “universal loving kindness.” It is the purest form of love that is free from desires and expectations, and loves regardless of the flaws and shortcomings of others.
Agape is the love that is felt for that which we intuitively know as the divine truth: the love that accepts, forgives and believes for our greater good.
Hopefully you will see a true representation of this love in these blog posts. 
Enjoy!
