Hi Upekkha100,
Jhana’s and brahma worlds can be enticing as you have pointed out in other discussion on this forum. But a point to keep in mind is that even if one gets to jhana and/or brahma worlds, if he is not an ariya, he will fall back down to the animal worlds and nirayas.
“An ordinary person stays there until the lifespan of those gods is spent, then they go to hell or the animal realm or the ghost realm. But a disciple of the Buddha stays there until the lifespan of those gods is spent, then they’re extinguished in that very life. This is the difference between an educated noble disciple and an uneducated ordinary person, that is, when there is a place of rebirth.”
So in my opinion it would be of more benefit to strive to attain maggha pala rather than jhana.
Just my thoughts on this.
