Constraints ? Not unless the end goal involves the behavior or feelings of another soul. For peace, go to the Author of Peace.
His table is spread before us and we are offered all. The constraints are rationalized not shackled. Rewards are proportional only to the energy applied.
Pray. It is the first step and can be taken without belief.
Read scripture. Even without belief it will speak to the heart.
Meditate, like aspirin it also requires no belief to create results.
Warriors of Light hold open hearts to receive their daily Directions. Each day is filled with surprises, most of them joyous. The ones without Joy can be returned. If we are willing to let go of them, He can fix them.
