There are physical aspects for prayers though stance is not among them because even a nice wave stance is still a constant that can be written down as an equation. Prayer comes to bring more life out of you and connect you to yourself. Prayer can come to you in the form of a vision of beautiful nature or a word from a friend and you are moved to prayer or you can choose to pray on your own in whatever situation you are and while you are engages in any action you choose. It is important to avoid becoming regimented in our minds. If for example you enjoy a ritual do so concisely rather than giving yourself to it. This way you choose it rather than being subjected to it. If you wish to use a wobble board simply place a plank on a basketball or a branch on a rock in nature and move freely rather than just back and forth or side to side. Try to advance and create rather than stay where you are. Our legs are for walking and if we let them, that’s just what they’ll do 🙂
