Allegiance to the denial of God is the ego’s religion. The god of sickness obviously demands the denial of health, because health is in direct opposition to its own survival. But consider what this means to you. Unless you are sick you cannot keep the gods you made, for only in sickness could you possibly want them. Blasphemy, then, is self-destructive, not God-destructive. It means that you are willing not to know yourself in order to be sick. This is the offering your god demands because, having made him out of your insanity, he is an insane idea. He has many forms, but although he may seem to be many different things he is but one idea;–the denial of God. T-10.V.3:1-8

The ego has a stake in denying the non dual Oneness of God for becoming aware of the non dual awareness of God of which we are a part the ego would no longer exist. The ego has a big incentive in continuing to seduce us with the things it offers enticing us with the hope that those things will make us happy. Not only do the things the ego offers us fail to make us happy, but they keep us from realizing the one thing that will: giving up the things of the ego and becoming one with the non dual Oneness, our Transcendent Source.
In Unitarian Universalism some of us join together to affirm and promote the free and responsible search for truth and meaning and this search takes us inward in search of the peace of God not outward in search of happiness offered by the things of the ego.
This search occurs in meditation and mindfulness. We can take time every day to withdraw our attention from the things of the ego and focus it on the peace of God. This can occur for a prolonged period of time or momentarily several times per day.
