“How is it possible that a Deva who is a Sakadagami, with his mind having sensuality will lose everything at the time of death and attain nibbana?”
There are two problems with the question:
1. A Deva, who is a Sakadagami, can attain Nibbana at any time, not just at the time of death.
2. Now, if we remove that part the question becomes, “How is it possible that a Deva who is a Sakadagami, with his mind having sensuality, attain nibbana?”
- Here, can’t we ask a similar question? “How is it possible that a human, with his mind having sensuality attain nibbana?”
- Any sentient being can attain Nibbana once the futility and danger of living in this world are understood FULLY.
- Of course, those in the apayas are incapable of comprehending Buddha Dhamma.
P.S. However, it is true that a Deva or a Brahma, who has not attained any magga phala, would have difficulty reaching even the Sotapanna Anugami stage (compared to a human.) It is easier for a human to see the futility and danger of living in this world because one can constantly see the suffering in the human and animal realms.
