It is impossible to describe the One. As it says in the Guru Granth Sahib:
If it is sayable, it is within the range of the word, If it is unsayable, it is outside the steady grasp of the mind, The real is where the sayable and the unsayable meet. What the real truly is, is altogether beyond comprehension (Guru Granth Sahib: 340).
Although people can say something about their relationship with the One there is a limit to what can be communicated through language. The implication of this is that the maps of the different religions, including Sikhi, can be used or ignored; what is important is the personal experience of the actual territory of the One. Guru Gobind Singh writes in a morning prayer: “I salute That which is beyond religion.”
