You already have the truth inside you.
Your attatchment to things you can't control can get in the way of your perception of truth.
Sitting meditation, walking meditation, pausing to find your center or start over, and the refusal to attatch to states of mind that induce suffering can help nip dukkha (dissatisfaction and suffering) in the bud.
Practicing mindfulness is like waking up in your life.
Faith in your abilities and in the process of Zen techniques such as meditation and mindfulness are necessary for finding your own truth.
