The existence of the paradise or heaven exists according to the belief of religious believers. However where people have got a little thinking capacity, they begin to disbelieve through the contradictions of various contending orthodox claims and descriptions because they ceases to exit without physical self/ego. Whatever is based on the physical self or waking entity or ego is bound to be falsehood because the physical self or waking entity or ego exists within the falsehood.
There is no need to condemn any religion or religious beliefs. But it is for the seeker of truth to find out how the religion becomes an obstacle in pursuit of truth for his own information. People hold any belief, any imagination they like in that realm. In religion the question of truth does not arise, only the question of what appears to one or what he believes in.
The religion is easy to follow because on has to only believe in the imagination propagated by it with blind faith. But the path of truth is verification of what one believes in. One may feel the path of truth is very difficult in the beginning but gradually as one becomes aware of the fact that, the self is not physical and learns to view and judge the worldview on the standpoint of the soul or consciousness, the innermost self, then it becomes easier to thread the path.
It is difficult for the religionists and intellectuals to tread the path of truth, because they base them selves on the physical self or waking entity or ego. But for the one, whom self-knowledge or Brahma Gnana or Atma Gnana is the supreme goal, who are ready to renouncing the ignorance, in order to realize the ultimate truth, and reflect on the soul or consciousness , the innermost self with devotion, becomes free from experiencing the illusory cycle of birth and death and become conscious of consciousness which is the true self and the eternal identity.
Theology is mere study, writing, research, or speaking on the nature of gods, especially in relation to human experience. Therefore, theology is based on the physical self or waking entity or ego. Whatever is based on the physical self or waking entity or ego is mere imagination or a theory based intellectual speculation without any finality.
Theological studies are usually done in religious institutions where the promotion of religious beliefs is part of the mission. Thus, theology is based on the false self or waking entity or ego; therefore it cannot yield any truth.
The seeker of truth has to move from unreality to reality, from ignorance to wisdom, untruth to truth, from mortality to immortality and diversity to unity.
