Hi Olivia,
I’m happy that you asked this question!
1️⃣ How to hold the mala:Always use your right hand. Hold it between the ring finger and thumb. Do not use the index finger (it represents ego and anger).
2️⃣ How to chant: Do not cross the main bead (Sumeru). When you finish one round, start in the reverse direction. Move one bead at a time using your middle finger while chanting.
There are different malas and chanting methods, but this is the most common way.
