Tien,
You say: “…when I laying down, Kama power seems to have multiply by 1000 and my Sati power decrease 1000 times”.
Recollect the devas. They are watching. Your unwholesome activities, whatever they be, even your unwholesome thoughts they can watch. Not as wardens – to observe, admonish and punish, but to ‘watch over’ rather, like tutors their pupils.
SN 55.34:
“…. these four footprints of the gods are in order to purify unpurified beings and cleanse unclean beings.
(experiential confidence in the Buddha, Dhamma and Sangha plus ethical conduct loved by the Noble Ones).”
And these devas ARE such Noble Ones.
SN 55.35/6 are on the same theme. SN 55.36 has:
“…when someone has four things the gods are pleased and speak of what they have in common”…
“There are deities with experiential confidence in the Buddha who passed away from here and were reborn there. They think: ‘Having such experiential confidence in the Buddha, we passed away from there and were reborn here.’ That noble disciple has the same kind of experiential confidence in the Buddha, so they will come into the presence of the gods.
“They think:‘Having such ethical conduct loved by the noble ones, we passed away from there and were reborn here. That noble disciple has the same kind of ethical conduct loved by the noble ones, so they will come into the presence of the gods.’ When someone has four things the gods are pleased and speak of what they have in common.”
That makes for encouragement alright. And remember, these devas are Ariyas, so ‘to go into their presence’ is only a station (for Sakadagamis) or 6 more at most(for Satopannas) short of Nibbana. It is not for the purpose of enjoying a deva bhava in itself and for itself.
