如鲸向海如鸟投林
[rú jīng xiàng hăi rú niăo tóu lín]
This phrase 'like whales diving into sea, like birds into forests' vividly illustrates following one's natural destiny or inclination. Whales find solace in the vast ocean and birds naturally head for shelter among forests – suggesting embracing instinctive direction and environment, akin to finding where one belongs.
