Do a wearer Rudrkaha has to perform any Pooja (prayer)?

As AstroMuni.Com provides its users with energized (Praanpratishthit)
Rudrakshas, the wearer doesn’t have to perform any Pooja (prayer) before
wearing it. But still it is recommended to chant the “Panchakshari Mantra”
of Lord Shiva for 11 times before wearing it. The Mantra is: “OM NAMAH
SHIVAYE”. In case of rosary of Rudraksha, it is always suggested to use it
for the purpose of chanting mantras related to any God. The more the
mantras will be chanted on Rudraksha Rosary, the more it will be energized,
thus giving its wearer more better results.
