Is it good to tell awakening stories? My question to all my dear friend is why people use to share there stories of awakening ?
will it affect the mind of others those who are meditating to find the inner peace.
I think at times it can be helpful, and at times, harmful.

The teachings of the Buddha are his experiences. By sharing his atainments, he helps us all walk the path. 

Unfortunately, if you are too descriptive, people will seek your experience in their practice. They may come to false conclusions that make guiding themselves toards the next attainment much more difficult. 

I think it may be more helpful to others if someone with attainments focuses on another's practice, and asks them to answer questions that spark introspection that leads them toward their next fruition.
