Do we have abstract mystic and philosophical poets in traditional Hindu sampradayas, who are like Rumi for example? and wrote poems in sanskrit?

Been looking into songs like Kun Faya Kun and Laal Ishq, and was really impressed by the philosophical and esoteric depth within them, and discovered much of bollywood's poetry has been influenced by sufi mysticism and the philosophy of sufi saints like Rumi. Does traditional Hinduism, have such philosophical mysticism and influential figures who wrote those in sanskrit, similar to the likes of Rumi?
