Non-attachment as object of meditation Is there text (e.g. suttas, and/or articles by modern authors) which describes &quot;non-attachment&quot; as an object of meditation? Specifically, how is &quot;non-attachment&quot; an &quot;object&quot;?
I'm asking partly because of this answer which says:

In the correct practise of Anapanasati, the meditation object is non-attachment. The resultant awareness of breathing is merely a sign (nimitta) that the mind is correctly non-attached.

I previously found texts reference more palpable meditation &quot;objects&quot;, e.g. Kasinas or breathing.
I once found something which seemed like it might be a meditation on non-attachment, towards the end of the Atthi Raga Sutta (SN 12.64):

Just as if there were a roofed house or a roofed hall having windows on the north, the south, or the east. When the sun rises, and a ray has entered by way of the window, where does it land?&quot;
&quot;On the western wall, lord.&quot;
&quot;And if there is no western wall, where does it land?&quot;
&quot;On the ground, lord.&quot;
&quot;And if there is no ground, where does it land?&quot;
&quot;On the water, lord.&quot;
&quot;And if there is no water, where does it land?&quot;
&quot;It does not land, lord.&quot;
&quot;In the same way, where there is no passion for the nutriment of physical food... contact... intellectual intention... consciousness, where there is no delight, no craving, then consciousness does not land there or increase.

However, literally, that's presented more as if it's a simile than as an object or type of meditation.
In the context of &quot;meditation on non-attachment&quot;, is awareness of breathing a symptom of attachment to (i.e. contact with) form and perception (or if not, why not)?
Have I misunderstood what's meant by &quot;the meditation object is non-attachment&quot; -- perhaps it means the &quot;the meditation goal, ambition, or purpose is non-attachment&quot;, but not &quot;the meditation focus or contact is non-attachment&quot;?
I think all these descriptions -  meditation on non-attachment, meditation with no goal, "just sitting", Diamond Samadhi etc. all refer to the type of meditation where your goal is to learn to be at peace with whatever happens in your phenomenal field - without either suppressing it or getting carried away by it.

One metaphor I heard to describe this, is the touch-and-go practice of the airplane pilots. You let the free-floating thoughts/emotions emerge and take shape just enough to get a flavor of each, but not to take over your awareness completely. You don't get attached to either the thoughtless state, or to any individual thought (or emotion) hence meditation on non-attachment.
