Faith and relaxation are intimately related. One cannot experience faith in tension. When one is physically relaxed, then the mind relaxes and is easy to experience faith. Faith is a moment in which one releases internally the mental and emotional tensions and the apparent control.
Physically speaking, it happens by deeply relaxing the body. The deeper one goes into the body the deeper and easier it is to surrender to the flow of existence. Fear creates tension everywhere. One can move out of fear by just observing and relaxing consciously those parts that are tense in the body. The egoic mind is going to ask to maintain the tension, because at the moment you surrender into relaxation the ego dies, if you pay deep attention an inner debate happens where you wish to relax and allow, your ego claims its place and wishes to maintain it dominion but if you continue relaxing, you will be able to see your mind calming and it is right at this moment that a strong spiritual transformation is happening.
As you relax silence arises and out of the silence faith can be experienced. That is the best place for prayer. It is right there, at that moment and place internally where if you release your prayer it will go straight to the source, to the Divine. There's no noise. Noise is the ego. Noise is the distraction that makes prayer non effective and empty.
Gratefulness is easily experienced when relaxed. Gratefulness and faith are very similar vibrations.
With meditation, yoga, taichi, qigong, pranayama, chanting and similar practices one learns how to relax, how to observe the body.
Another link into relaxation is the breath. I will write more about this in another post.
The mindfulness meditation and prayer course is very effective to teach this.
This could be one of the most important things to learn. Learn to relax, this is a basic spiritual instruction. Basic but transcendental.
God bless you much always and the very best to your life,
