“……..you do not arrive here by just straining your neck to look at the mountain.
You must start out and continue on.
You have to leave the place,
where everyone worries about rank and money,
where dogs bark and stay home.
Up here it is music and poetry and divine wind!”
~Rumi in Mountaintop Trough
Yes that’s what being non possessive would feel like. A sense of freedom ( where there is just Music, poetry and divine wind!) once one eliminates the sense of doership and deservership.
To start, one can treat all articles, beings and circumstances in one’s life as a loan from Him. One may need to keep on reminding oneself over and over until it sinks in. Small notes all over ones home/ work and even phone alert saying- ‘LOAN, Leave it alone’ or something on those lines may keep one on track.
So when everything is a loan, then I don’t own anything. There will be no possessiveness.
