The Beatles sang “All you need is love” in our times. Then there is another song on ‘Love’ that the celestial being, Pañcasikha, wrote to his ladylove in the time of the Buddha. Pañcasikha approached the Buddha and playing on his vinā, sang of the parts of the body of his ladylove that he loves as much as the Arahants love the Dhamma. The song that this Deva sang talks about both of the carnal love of passion, and of the altruistic love of the Triple Gem. Our question here is how we can see this other “Love” through Dhamma.
The love that we project in the loving-kindness (Metta) Meditation is the true love that one exercises toward oneself and others. We spread this other-worldly ‘love’ that is altruistic in nature in two ways. The two methods are Appamānha Chētō Vimukkti and Mahaggata Chētō Vimukkti. Loving-kindness meditation is meant to be a challenge for you to really think through as to why you would want to limit your love, and to remind yourself of why it’s good to have love for everyone. In this guardian meditation, we spread love direction-wise without any limit. Also we can spread loving-kindness by expanding the area of focus progressively.
As a person progresses deeper into Dhamma, he/she discards the false values in self, in cultivating awareness and a love that is altruistic and unselfish. When a person gets into the Noble Eightfold path, he/she rises above the "fetters" (samyojana) of (1) personality view, (2) doubt, (3) clinging to rules and rituals. This person is then possessed with qualities of honesty, uprightness, benevolence, altruistic joy, magnanimity, modesty and humility. The negative qualities of deceit, cunning, hypocrisy, jealousy, avarice, feelings of self-importance and arrogance are not found in one who begins to walk the Noble Eightfold Path. So to your question, Love still exists, but goes beyond to a level of limitless that is difficult to fathom.
