The Greek had four words for it; Sanskrit has many; Arabic distinguishes love (hubb) from passionate love (ishq) and compassionate love (rahma). Every tradition that takes love seriously first separates out what is being named.
Bhakti and Sufism treat love as the path itself — and not love in a diluted sense. In Rumi and Mirabai the lover is undone, burned, annihilated in the Beloved. This is not romance; it is ontology. The self is dissolved in what loves it.
In Christianity‘s Agape and in Buddhist Metta, love is cultivated as practice — the direction one can point the heart. Start where you can; extend outward.
