It is mentioned in the first talk that once one reaches sakadagami stage one will not experience
any physical discomfort because of the nature of their subtle bodies in the deva realms.
I am wondering if these entities out of compassion, able to help and guide those in the lower stages to come out of their predicament?
Can a arhant guide humanity if he/she wishes to do so, or do they cease to exist?
I have also heard that the Buddha had made statements that it is wrong to say that an arhant exists or ceases to exist after arhanthood (it is neither).
It is a general understanding in most major religions that the ones who have reached higher stages
help others to progress.
