What is the meaning of “enters & remains”?
“There is the case where a monk, quite secluded from sensuality, secluded from unskillful mental qualities, enters & remains in the first jhāna: rapture & pleasure born of seclusion, accompanied by directed thought & evaluation. AN 9.32
Buddha teaches to “direct” and “incline” thoughts. He also speaks:
The Blessed One said: "There is the case, monks, where an uninstructed run-of-the-mill person — who has no regard for noble ones, is not well-versed or disciplined in their Dhamma; who has no regard for men of integrity, is not well-versed or disciplined in their Dhamma — perceives earth as earth. Perceiving earth as earth, he conceives [things] about earth, he conceives [things] in earth, he conceives [things] coming out of earth, he conceives earth as 'mine,' he delights in earth. Why is that? Because he has not comprehended it, I tell you. MN 1
Furthermore, the Buddha says:
2. There are, beggars, ten kasiṇa[1] deployments.[2]
What ten?
One perceives the earth-kasiṇa above, below, across, united, immeasurable.
One perceives the water-kasiṇa above, below, across, united, immeasurable.
One perceives the firelight-kasiṇa above, below, across, united, immeasurable.
One perceives the wind-kasiṇa above, below, across, united, immeasurable.
One perceives the blue-kasiṇa above, below, across, united, immeasurable.
One perceives the yellow-kasiṇa above, below, across, united, immeasurable.
One perceives the red-kasiṇa above, below, across, united, immeasurable.
One perceives the white-kasiṇa above, below, across, united, immeasurable.
One perceives the space-kasiṇa above, below, across, united, immeasurable.
One perceives the consciousness-kasiṇa above, below, across, united, immeasurable.
These then, beggars, are the ten kasiṇa deployments.AN 10.25
Is the earth kasina, for example, the “comprehension” of earth which the Buddha refers to in MN 1? And if the kasina is indeed “everywhere” then what does it mean to
enter & remain there? Or is kasina comprehension simply another perversion about the object?
