Another symbol used by Baháʼu'lláh in describing the Haykal is through the four letters (H, Y, K, and L) that compose the word in Arabic. Baháʼu'lláh in the tablet explains the spiritual significance of each letter: H is for Huwiyyah (Essence of Divinity), Y is for Qadír (Almighty), K is for Karím (All Bountiful), and L is for Fadl (Grace).
