Any ritual can help if done with the right frame of mind.
Some creative rituals are downright strange.
One writer had a particular record of Spanish flamenco music he listened to before he started to write. The ritual itself is usually not directly related to creative thinking but is a means of focussing the mind on producing ideas and is a very personal thing. What works for one person will probably not work for another. Remember that a ritual is an external method, whereas creativity is personal and individual.
