It is very well known fact that whenever we, the human beings are in any type of trouble we look for some superior power or a force to help us and get rid us out of the problem. Now what can be a better solution for this than the almighty God who himself has created us.
It is for this very purpose that our ancient sages developed a way to communicate and convey our problems to almighty God for getting rid of our problems or seek the divine blessings to save us from impending problems via certain specific procedures which are known as Puja and Homas.
Puja is the act of showing our faith and respect to a God, a spirit, or another aspect of the divine through invocations, prayers, songs, and rituals thereby making a spiritual connection with the divine. Most often this contact is facilitated through an object: an Image, element of nature, a sculpture, a painting, or a print. It is a well known fact that the entire universe along with all its planets have been created by the supreme power ( God ) and hence it is also possible to reduce one's sufferings due to the unfavorable position of planets through sincere reliance on God by performing the necessary Puja.
During Puja, an image or other symbol of the god serves as a means of gaining access to the divine. This icon is not the deity itself; rather, it is believed to be filled with the deity's cosmic energy. It is a focal point for honoring and communicating with the God.. The objects are created as receptacles for spiritual energy that allow the devotee to experience direct communication with his or her Gods.
