The lamps are different, but the Light is the same
Rumi uses the lamp-and-light distinction to argue that religious traditions differ in their outward vessel, not in the reality they were built to carry.
In Book I of the Masnavi, Rumi develops this idea partly through the parable of four travelers — a Persian, an Arab, a Turk, and a Greek — who are given a coin and fight over what fruit to buy with it, each demanding a different word for grape without realizing all four words name the same fruit. Their conflict is entirely linguistic, not substantive, and Rumi extends the point to religious forms generally: the specific practices, laws, and vocabularies of different faiths are the lamps, shaped by history and culture, while what they exist to illuminate is one and the same Light across them. This was a striking claim for a thirteenth-century Muslim jurist-turned-mystic to make in a didactic poem meant for religious instruction, and it remains one of the most frequently cited grounds for reading Rumi as a pluralist rather than a sectarian teacher. The teaching does not erase the value of the lamp — one is still needed to see by — it only relativizes rival lamps against the single Light they share.

- What Sufism says about doubt
Rumi develops this through four travellers given one coin, each demanding a different word for grape and fighting over it. Their conflict is linguistic, not substantive. Extended to religious forms, the practices and vocabularies are lamps, which means the argument you are winning may be about words.
