We live and keep ourselves alive because of cosmic energy. Due to fluctuations in the cosmic energy, certain deficiencies occur in the human body which create numerous problems. Copper, being a good conductor, plays an important role in keeping these fluctuations under control. Just as electricity is generated in a power house and through the distribution transformer and copper cable it reaches the meter in our house and we are able to make good use of the electrical equipment / gadgets. To safeguard these equipments/gadgets, we install a voltage stabilizer. In the same manner, kara, made out of copper wire, blessed with sacred mantras, receives cosmic energy, stores it and distributes/transmits it to the human body at required intensity, so that various gadgets/limbs of our body are able to perform the desired functions. Kara is worn as a protective measure to safeguard our body and to maintain its normal functioning. This is the reason why, Kara keeps changing its colour – at times it shines, sometimes it becomes dull and at times it turns black or red. This is a scientific explanation.
Copper is a metal that acts as a shield or a deterrent to any impending ailment. From naturopathy point of view, water stored in a copper vessel, eliminates the impurities of water and its use can drive out many anomalies of the stomach. Copper kara constantly rubs around the wrist and, through the fine pores of skin, enters into our body in an infinitesimal quantity. Then it mixes with the body chemistry and eradicates many types of ailments.
The copper kara has a very deep spiritual significance also. Copper is a manifestation of Mahamritunjey (one of the forms of Lord Shiva), that not only gives relief from ailments, sorrows, sufferings and other problems, but also acts as a protection to the human body and bestows good health. After living a complete life, it ensures agony-free transcendence.
Half copper and half silver kara symbolically is a manifestation of Shiva and Shakti. Shakti, in the form of Goddess Lakshmi, bestows upon us happiness and well-being, wealth and prosperity, progress and advancement in business and profession.
It needs to be clearly understood that when you take these items – sanctified (blessed and infused with spiritual powers) – with pious feelings, implicit faith and reverence, surrender yourself unconditionally unto the lotus feet of your Guru and God, the results and blessings are equally positive and forthcoming. For example, while bowing your head before the Guru to receive his blessings, if the inner-self has not bowed, then, the mechanical bending of the body is meaningless. If a karma is performed half-heartedly, devoid of faith and reverence, then the result obtained is also incomplete. A true Sadguru, who renders selfless service, expects nothing in return; he only yearns for love and reverence. Except love, reverence and faith, what else can you give to your Guru. In the spiritual domain of Guru hierarchy, gift items of material world are unimportant and meaningless. To detach yourself from the material world and move ahead towards the spiritual attainment is the ultimate goal of human life.
