Etymology
性 combines 忄 (heart/mind) with 生, which likely contributes both sound and the idea of life or birth, suggesting the innate qualities one is born with.
Meaning mnemonic
The heart radical 忄 beside life 生 points to the inner, inborn qualities of a living being: its sex and its nature.
Reading mnemonic
For セイ, imagine a sage explaining the nature of all things: sage -> セイ, and the sage's wisdom reveals the true nature of life.
