Where can I buy Manjusri Bodhisattva dice?

It is best to learn the method of divination after you have finished the necessary exercises. Although Sodagi Kampo has let you learn, if you finish the mantra and practice in the required way, your accuracy will be high, otherwise you will be afraid of poor accuracy.

I used to ask the guru for Guanyin hexagrams, but the guru didn't give me permission, because I didn't practice yoga, and I didn't finish reading the number of heart spells to learn hexagrams, hehe.

It is better to practice these methods first and learn divination after getting permission from the guru.
