as we all know there are several ideas around of what and how Jhana is supposed to be.
Now, for all who trust in th Suttas, here is one that contradicts the widely believed version of jhana being a one point concentration method, where "jhāna is a state of uninterrupted absorption in an object".
Have a look at venāngapurasuttaṃ (venānga), that is AN III 63(or 64).
“But, Master Gotama, what is the celestial high and luxurious bed that at present you gain at will, without trouble or difficulty?”
“Here, brahmin, when I am dwelling in dependence on a village or town, in the morning I dress, take my bowl and robe, and enter that village or town for alms. After the meal, when I have returned from the alms round, I enter a grove. I collect some grass or leaves that I find there into a pile and then sit down. Having folded my legs crosswise and straightened my body, I establish mindfulness in front of me. Then, secluded from sensual pleasures, secluded from unwholesome states, I enter and dwell in the first jhāna, which consists of rapture and pleasure born of seclusion, accompanied by thought and examination. With the subsiding of thought and examination, I enter and dwell in the second jhāna, which has internal placidity and unification of mind and consists of rapture and pleasure born of concentration, without thought and examination. With the fading away as well of rapture, I dwell equanimous and, mindful and clearly comprehending, I experience pleasure with the body; I enter and dwell in the third jhāna of which the noble ones declare: ‘He is equanimous, mindful, one who dwells happily.’ With the abandoning of pleasure and pain, and with the previous passing away of joy and dejection, I enter and dwell in the fourth jhāna, neither painful nor pleasant, which has purification of mindfulness by equanimity.
“When I am in such a state, if I walk back and forth, on that occasion my walking back and forth is celestial. If I am standing, on that occasion my standing is celestial. If I am sitting, on that occasion my sitting is celestial. If I lie down, on that occasion this is my celestial high and luxurious bed. This is that celestial high and luxurious bed that at present I can gain at will, without trouble or difficulty.”
