Puja and Homa is necessary because it is a procedure of showing your reverence to the deity - the store house of divine powers and spiritually getting connected with it. It is the procedure by which the desire of a person can be spiritually communicated to the deity so that it get fulfilled.

As a general human being our power is limited. But it has been proven by several God men who came to know this through meditation that our origin is nothing but a same source ...the source of spiritual power ...super power ...Param Bramh. Our so called God and Goddess are the idolised symbols of this super spiritual power. By offering Puja and Homa to our God and Goddess a person get connected with this super power. Puja or Homa is basically a powerful spiritual procedure and if it is properly done, a person may get it's result sitting thousands of miles away from the temple. If you can perform puja physically then it is further better if you get someone who honestly offer Puja on behalf of you in a particular temple although you may not be present there at the time of your Puja.

Puja makes our body and mind holy and pure. It keeps our unrest mind cool. Puja is also the unconditional surrender of ourselves ...OUR BODY AND SOUL to the divine power which took pity on us, put mercy and wash away all our sins and teaches us from our within what to do and what not to do. Puja and Homa in many times fulfill our desires ...rescue from the dangers ...bring us to the point of prosperity ...and give us a glimpse of touches of blessings of the deity which fill up our body and mind with a different feeling and give rise an eternal peace. Puja gives us the strength to confront with adverse situation and get the victory.

Puja is a yoga ...Puja is a meditation which connect us with the divine (Jeeva with Shiva).
