It is not fair that seetha Devi had to enter into fire to prove her purity to Sri Rama and the entire world. It is not fair that Sri Rama killed a great warrior Wali. It is not fair that arjuna Killed Karna while he is off his chariot. All of were brought with questions related to incidents depicted in our Puranas. Further we also had doubts about day to day rituals like to Pranamam to God.
Temple is a place where Gods and Goddess are invoked. In sanskrit the innovation process as called Prathista. During the Prathista gods and goddess are invited to the place where the temple has been built and the specific gods and goddess are asked to be present in the idols that are made of black stone or marble stone. All this process of inviting gods and goddess to be in the idols is done with the Veda mantras, sacred rituals and Homas.
Many hindus worship and pray at home. It is usual practice to have a small prayer room in any hindu home. Mostly the gods and goddess are in one’s prayer room at home are pictures of gods and goddess and are framed. When we go to temple we see many devotees who come to worship and pray. Because of gods and goddess’s presence there is already enormous amount of energy that doesn’t exist at home. Every person carries some amount of energy. When enormous energy of gods and goddess and little energy of humans combine at one confined place, the amount of energy that is totaled becomes huge. In addition to this, chanting of Veda Mantras, recitation of sthotras singing of songs and bhajans performances of traditional dances etc add extra energy to the place. The Holy water, Blessing and Prasadam that we get at temple cannot be found at home
