Pooja is a sacred practice performed on different occasions to worship, pray or show your due respect to the God. To explain better, Pooja is as an act of showing reverence to the almighty through invocations, prayers (like mantra, slokas), songs, rituals and so on. Praising the God through poojas helps establish a spiritual connection between the deity and the devotee.
To get rid of negative influences in life and to attain good luck and enlightenment, pray to Lord Ganesha. He has the power to bless you with a trouble-free life. Conducting Poojas and archanas to him will help invoke his blessings, you will lead a trouble-free life and will attain good luck and enlightenment throughout your life! If one suffers from losses, wants to start a new business or invest in a good career, Maha Ganapathy pooja is recommended.
Fire has been an important part of human culture since the Paleolithic age. Worshipping the Fire God, will benefit you immensely and grant you with whatever you ask for. A Fire Ritual/ yagna/ homa is the strongest remedy to alleviate karmic difficulty. It is a Vedic ceremony performed either at a dedicated Hindu temple or even at your home with the help of sanctified priests. During the ritual the consecrated priests continuously chant specific astrological mantras (sounds). The priests will also make offerings such as rice or clarified butter, to invoke planetary deities or the gods, so that grace and intervention may be given to the person requesting the remedy. A day or two after the remedy, the person may experience a relief from his/her negative karma, which often feels like a heavy weight that has been lifted off one's shoulders.
Ganesha is considered the "God of Luck". Before beginning any new venture or anything afresh, Ganesha homa is recommended to keep away from obstacles.
