Feelings are like clouds in the sky. They are seen, but we don't build our houses on them. Clouds come and go, sometimes bringing rain and wind and sometimes not.
SN36.19:5.3: In one explanation I’ve spoken of two feelings. In another explanation I’ve spoken of three feelings, or five, six, eighteen, thirty-six, or a hundred and eight feelings.
Clouds are beautiful and mesmerizing. Liking feelings and clouds, we might even chase them:
SN32.13-52:1.11: ‘If only, when my body breaks up, after death, I would be reborn in the company of the gods of rainy clouds!’
SN32.13-52:1.12: They give food …
SN32.13-52:1.13: a lamp.
SN32.13-52:1.14: When their body breaks up, after death, they’re reborn in the company of the gods of rainy clouds.
SN32.13-52:1.15: This is the cause, this is the reason why someone, when their body breaks up, after death, is reborn in the company of the gods of rainy clouds.”
And if cloud-chasing proves unfruitful, we might then stubbornly ignore clouds, trying hard to be numb to clouds, stopping or repressing any kind of feelings that may arise about clouds. But if we become numb to clouds, we'll likely be surprised by storms on some days and sunburned on other days.
However, if we watch clouds carefully, with equanimity, we might gain insight and be better served by knowing when to plant, when to harvest and when to seek shelter. Watching clouds very carefully, we gain insight into their coming and going. That very insight leads to a peaceful pleasant feeling that is finer than chasing clouds or feelings.
SN36.19:6.12: Because there is another pleasure that is finer than that.
SN36.19:7.1: And what is that pleasure?
SN36.19:7.2: It’s when a mendicant, quite secluded from sensual pleasures, secluded from unskillful qualities, enters and remains in the first absorption, which has the rapture and bliss born of seclusion, while placing the mind and keeping it connected.
Equanimity allows us to observe carefully. And what do we observe carefully? Well, the second of the four mindful meditations is actually the meditation on feelings. We observe feelings rid of desire and aversion.
MN118:25.1: Whenever a mendicant practices breathing while experiencing rapture,
MN118:25.2: or experiencing bliss,
MN118:25.3: or experiencing these emotions,
MN118:25.4: or stilling these emotions—
MN118:25.5: at that time they meditate observing an aspect of feelings—keen, aware, and mindful, rid of desire and aversion for the world.
MN118:25.6: For I say that close attention to the in-breaths and out-breaths is an aspect of feelings.
In other words, we observe feelings undisturbed by them. We observe, "this is a pleasant feeling." We observe, "this is a painful feeling." We observe, "this is a neutral feeling."
If we watch clouds with equanimity, we might see the ocean that gives rise to the clouds. We might see the mountains that catch the rain and channel it to the sea via streams and lakes. With equanimity we might see beyond the clouds, beyond the feelings:
AN10.61:4.1: It’s like when the rain pours down on a mountain top, and the water flows downhill to fill the hollows, crevices, and creeks. As they become full, they fill up the pools. The pools fill up the lakes, the lakes fill up the streams, and the streams fill up the rivers. And as the rivers become full, they fill up the ocean.
