A few questions!

Hello! I'm pretty new to hellenism and worshipping the Gods. To make this relatively short and to the point...:

Question 1: What are the different ways to cleanse something? For example, I do not have access to a lot of normal, typical things one might use to cleanse crystals or different divination tools, etc. I was wondering if there's a way to still cleanse things without all of the "fancy stuff", so-to-speak.

Question 2: Any tips on hand crafting a pendulum if I cannot buy one? I really wanna make one, but again I have very limited resources 🥲.

Basically, my parents are strict Christians and would actually probably k!ll me if they found out I follow Hellenism instead of Christianity. Meaning, I can't buy incense or candles or crystals without them getting overly suspicious.

Thank you! <3
