Copper is a metal that can create a certain energy and assist in meditation. Bringing it in contact with the body can help to strengthen and stabilize one’s energy system.
If you are tying a knot on either side of the Rudraksha, care must be taken not to tie it too tight as this could make the inside of the Rudraksha crack. If the inside crumbles with the pressure, the rudraksha should not be worn. Also, make sure not to cup the Rudraksha.
