Accepting death and spirituality in a healthy way with love rather than fear requires a lot of faith in the higher power or God.
This faith, however, is not mere blind faith because it is backed with reasoning that proves the prowess of the Almighty Lord rather than knowledge gathered by limited sense perception and motivated by false ego.
Thus, relying on the knowledge and understanding derived from the revealed scriptures, strengthened by wisdom is highly beneficial.
It helps build trust and faith. Furthermore, you can take inspiration from famous quotes, proverbs, and sayings.
