divining, fortune-telling, divination or katakana to radical (no. 25)
卜 centers on seeking hidden knowledge through signs: divining, fortune-telling, or reading omens. The radical sense is the same shape used as a component in other characters.
卜 is a pictograph of a crack in a heated oracle bone, representing the practice of divination by interpreting such cracks.
The two strokes look like a crack on a heated bone or shell used for fortune-telling. Picture a diviner reading the crack to tell the future.
For ボク, imagine a fortune-teller knocking on a wooden box to summon spirits: box -> ボク, and the crack on the bone reveals the answer.
