And also how do you powder bay leaves without a grinder? Thank you.
ANSWER - I'm not completely sure I understand your question. Transformation for what? There are many herbs that will aid in transforming your mind and even your astral self but without defining exactly what you mean by transformation, its hard to advise. If you let me know what you mean, I'll answer the question again for you and give you some specifics depending on what you are looking for.
In terms of the bay leaves, it depends really whether you are making something you intend to eat or not. If it is something you do not intend to consume, dry the bay leaves and use a pestle and mortar to grind them up with something crumbly like a small piece of brick. Just using the pestle and mortar (buy one cheap in any supermarket by the way) won't be effective on its own.
If however you intend to consume whatever you are making with bay, you may be better to make an infusion of the leaves in oil. Simply steep two or three leaves in a few spoonfuls of olive oil and leave for a day or two for the oil to absorb the essence of the bay.
