Here’s the full quote from Thomas Merton, now that I’ve got the New Seeds of Contemplation checked out from the library.
Fickleness and indecision are signs of self-love.
If you can never make up your mind what God wills for you, but are always veering from one opinion to another, from one practice to another, from one method to another, it may be an indication that you are trying to get around God’s will and do your own with a quiet conscience.
As soon as God gets you in one monastery you want to be in another.
As soon as you taste one way of prayer, you want to try another. You are always making resolutions and breaking them by counterresolutions. You ask your confessor and do not remember the answers. Before you finish one book you begin another, and with every book you read you change the whole plan of your interior life.
Soon you will have no interior life at all. Your whole existence will be a patchwork of confused desires and daydreams and velleities in which you do nothing except defeat the work of grace: for all this is an elaborate subconscious device of your nature to resist God, Whose work in your soul demands the sacrifice of all that you desire and delight in, and, indeed, of all that you are.
So keep still, and let Him do some work.
This is what it means to renounce not only pleasures and possessions, but even you own self.
The last thing I want to do is defeat the work of grace. God help me.
