When we look at the major religions specially the abrahamic religions the norm today is it is enough to belive in God or Jesus to get to heaven. But it is really that easy?
In most Asian religion the teachings say do this (the there are guidelines) and you will see progress, and if you do really well you reach enlightenment ( you must walk the path you self, not just get taken up by Buddha or Shiva if you believe in them)
Should humans not do their best to do what the religion say "they should do" instead of just Yes i belive and now i go to heaven?
I do not judge anyone who do have the belief of "now i belive then i go to heaven" I only ask the question because i not sure i understand how it would be possible.
In main stream Islam and Christianity it is thought that it is enough to believe in the faith and be a good person, i.e. to perform a limited set of religious duties such as attend church or a mosque, do some good deeds and praying and behave well in the community.
With some born again Christians there is an attempt to plunge into some form of cosmic or God ideation and surrender one's everything to God's will, which I guess goes towards a form of mysticism. Such Christians may even use
mudra in order to reach more of a state of surrender when they dance in praise with their hands up in the air.
In the more Tantric systems such as in Yoga and Sufism, there is even more of an effort to actively associate and merge the individual self with its Cosmic or selfless Center (sometimes associated with "Emptiness", sometimes with God). Rather than using the more extroversial system of verbal prayer, they will choose to use meditation and other techniques to weaken the boundaries of the self. There are also good deeds and good behaviour but these are well embedded in an ideation of selflessness (lack of ego in the actions) often strongly connected to serving the Beloved or God.
Some born again christians will stress that your being saved does not depend on you actions but only on your faith. This need not be a false idea if it is understood well enough what faith actually means in this case. Faith here means that your whole being (including your actions) has been surrendered to the Lord or your Higher Self. This is not the same as simply believing or accepting a faith in words. It is not a switch which can just be turned at will. It depends purely on grace and requires your total surrender. And that can better be achieved through Tantric practices than through extroversial religious (Vedic) practices such as prayers or rituals.
