Rudraksha
The word rudraksha is derived from two words – rudra (रुद्र) and aksha (अक्ष). Aksha means eye. Rudra and aksha means the one who is capable of looking at and doing everything (for example, the third eye). Aksha also means axis. Since the eye can rotate on one axis, it too is known as aksha. Rudra means the one who weeps. A (अ) means to receive and ksha (क्ष) means to give. Hence, aksha (अक्ष) denotes the ability to receive or give. Rudraksha is the one that has the ability to wipe our tears and provide happiness.
Rudraksha is a kind of shield against negative energies. It is possible for some people to use negative energies to cause harm to someone else. This is a whole science by itself. One Veda, the Atharvana Veda, is all about how to use energies to your advantage and to someone else’s detriment. If somebody who has mastery over this wants to use it, so many things—extreme suffering and even death—can be caused.
