Sufism is the school of Islam that is more inward-looking, that is about devotional love to God. And that's what a lot of Sikhism is focused on. But as mentioned, one could also think about Hinduism, which is much older than pretty much any other living religion today. And in other videos, we talk about the bhakti movement, which is about devotional love to God. There's also a school of thought in Hinduism known as Vedanta, which is more focused on the core spiritual ideas of the Upanishads, the notion of the ultimate self, the ultimate reality, escaping from the cycle of births and deaths, from samsara, achieving liberation, moksha. All of these ideas are in Sikhism. And to make the point clear that all of our major religions are connected to each other, we can keep drawing this tree.
