I should thank Pendragon for his comment on definition of Love :nod:.
Speaking of Bible, there are several types of love mentioned there, which are closely related to Greek's definitions:
Agape - is charitable, selfless, altruistic, and unconditional. It is parental love seen as creating goodness in the world, it is the way God is seen to love humanity, and it is seen as the kind of love that Christians aspire to have for one another.
Phileo - a human response to something that is found to be delightful. Also known as "brotherly love".
There are two other types of love, Eros (sexual love) and storge (needy child-to parent love), which are said never mentioned in the Bible.
However, I'm not really sure whether they're never mentioned. For example, I think the story of David and Bathsyeba is a good example of Eros.
As we already have good exposure of love from Christianity, I suppose it's also a good idea to disscuss about love from other religions' point of views:
Buddhism/Hinduism:
Kāma is sensuous, sexual love. It is an obstacle on the path to enlightenment, since it is selfish.
Karuā is compassion and mercy, which reduces the suffering of others. It is complementary to wisdom, and is necessary for enlightenment.
Advea and maitrī are benevolent love. This love is unconditional and requires considerable self-acceptance. This is quite different from the ordinary love, which is usually about attachment and sex, which rarely occur without self-interest. Instead, in Buddhism it refers to detachment and unselfish interest in others' welfare.
In Hinduism, there's also Bhakti, which is a Sanskrit term from Hinduism meaning 'loving devotion to the supreme God'. A person who practices bhakti is called bhakta.
Islam:
In a sense, love does encompass the Islamic view of life as universal brotherhood which applies to all who hold the faith. There are no direct references stating that God is love, but amongst the 99 names of God
(Allah), there is the name Al-Wadud or 'the Loving One', which is found in Surah 11:90 as well as Surah 85:14. Also, there's also this term, Ishq, or divine love, which is the emphasis of Sufism. Sufis believe that love is a projection of the essence of God to the universe.
Judaism:
In Hebrew Ahava is the most commonly-used term for both interpersonal love and love of God. Other related but dissimilar terms are Chen (grace) and Hesed, which basically combines the meaning of "affection" and "compassion" and is sometimes rendered in English as "loving-kindness".
(source: wikipedia)
From those definitions, I suppose all these main religions of the world share more or less same definition on Love. Except Buddhaism, other religions share the thoughts that certain love is closely related to God and human relationship towards divine being. On the other hand, there are types of love which are self centric or closely related to personal and interpersonal relationship relationship.
What do you think?
