Two types of growth
There are two types of growth. One which you can do something about; and another, which you cannot do anything about.
For one, your effort is needed; and for the other, your effortlessness is needed. Spiritual growth is of the second type.
Your effort will be of no help; it will only create barriers. You cannot do anything about spiritual growth.
The only thing you can do is to surrender and that is a non-doing. You can only do one thing: allow the divine to work within you. You can simply cooperate that’s all. You can simply float, your swimming is not needed — a deep let-go.
