strive, flourish
懋 centers on putting forth vigorous effort so that something grows or thrives: striving hard and flourishing as a result.
懋 combines 楙 (likely contributing the sound and the idea of lush growth) with 心 (heart/mind), suggesting a heart-driven effort that leads to flourishing.
The top part 楙 looks like a dense thicket of plants striving upward, and the bottom 心 is the heart pushing them to grow. Together they show a heart that strives until things flourish.
For ボウ, imagine a bow (as in bow and arrow) being pulled back with great effort, then released to make something flourish: bow -> ボウ.
