Discipline, strictly speaking, is activity carried on to prepare us indirectly for some activity other than itself. We do not practice the piano to practice the piano well, but to play it well.

We are invited to make a pilgrimage – into the heart and life of God.

What we think is, in the adult person, very much a matter of what we allow ourselves to think, and what we feel is very much a matter of what we allow ourselves to feel. Moreover, what we think is very much a matter of what we wish and seek to think, and what we feel is very much a matter of what we wish and seek to feel. In short, the condition of our mind is very much a matter of the direction in which our will is set.

In Spiritual formation we are aiming at a character and life that is so shaped that the deeds of Christ routinely and easily come from what is inside.

Solitude well practiced will break the power of busyness, haste, isolation, & loneliness.

The revolution of Jesus is in the first place and continuously a revolution of the human heart or spirit...it is a revolution of character which proceeds by changing people from the inside through ongoing personal relationship to God in Christ and to one another. It is one that changes their ideas, beliefs, feelings, and habits of choice, as well as their bodily tendencies and social relations. It penetrates to the deepest layer of their soul. External, social arrangements may be used to this end, but they are not the end, nor are they a fundamental part of the means

Spiritual formation cannot, in the nature of the case, be a 'private' thing, because it is a matter of whole-life transformation. You need to seek out others in your community who are pursuing the renovation of the heart.
