It allows integrity. It integrates the entire being of a person around a worthwhile goal.
A Spiritual Path is not just for the one embarking on this path it is for all life everywhere in the Universe.
The thought often is: "I am suffering! I see everyone suffering! How can we all end our suffering and have worthwhile lives?"
This leads to withdrawal from the world in trying to find an answer to your personal suffering and the suffering of all beings.
This often leads to making a plan of how to go about ending your suffering and the suffering of all others.
If one's plan is not suicide as an answer then one goes forward on a Spiritual path as a Seeker of Wisdom, knowledge and Compassion.
If one is true to oneself and all life in the universe and doesn't ever completely give up: Answers are found coming from literally anywhere and everywhere. Sharing these realizations with oneself and others often saves and lengthens their lives too making everyone's life potentially better ongoing into the future!
