Invocation - 調用 - Diàoyòng
Spiritual growth cannot occur automatically.
A declaration of belief must be voluntary.
To invoke one's faith, it must be understood-
worship becomes recognition.
Blessings of faith mature over time,
eventually providing a glimpse
through the void, of the source.
~Inspired by Deng Ming-Dao
Early in the study of Tao, all practices and rituals are externalized, merely procedural. At times, it is difficult to find significance in these actions. Everything is unexpected. This is the proper order. It is too early in instruction to interfere with growth and discovery. This may cause followers of Tao to be hesitant to move beyond technical instruction.
Look at worship, for example. At first, an invocation is an external act. You repeat it, but initially, it means very little. Kneeling down to the altar, you realize you only do so to have something to focus upon. Once you realize the real Tao is bound to be within yourself, you must shift your focus. Worship has become recognition. Your own spirit rises, and you learn to tap into that spiritual energy. If you simply waited for someone to tell you what to look for, you would never be sure of your own experience. What comes from outer suggestions cannot be the true Tao.
However, once you have glimpsed the source, there are no doubts.
