pray
祷 centers on the act of praying, specifically making a request or offering to a deity or spirit.
祷 is the modern simplified form of 禱. The older form combines 示 (altar, spirit) with 壽, which likely contributed the sound and the idea of long life or blessing. The modern right side 寿 is a simplification of 壽.
The left side 示 represents an altar or spirit. The right side 寿 suggests a long life. Picture kneeling at an altar, praying for a long and blessed life.
For トウ, imagine praying at a tall tower: tower -> トウ, and your prayers rise up from the altar.
