@Good-boy No one is going to prove anything to you.
Sit down and self-inquire. All else is you just running away from truth like a scared little girl.
You don't actually believe you are a body. You believe you own the body, therefore it is not you (by your own deluded logic).

I took some action steps (baby steps) to figure this one out. For example, I love art, but it's not so easy to market art all by itself. I love making things, so I made these colorful, decorative, small baskets wrapped with chocolates inside and sold them as birthday return gifts (goody bags) at children's birthday parties. Of course, sweethearts also bought them to give to their bf/gf. The demand grew, and I couldn't keep up with the demand. I was making at least 30 baskets a day and staying up till 3 AM sometimes to meet those demands. It wasn't working out - too exhausting.
I had to change this art path slightly. After much thinking, I decided to incorporate language into my art. So, I decided to learn Mandarin, a pictorial language. I made a website and wrote a book in both English & Mandarin and did some networking. I met the founder of a school, who was also an investor and my mentor and he hired me as a bilingual teacher. I teach children in crafty ways. That's my career, but I'm still working on my life purpose which will also involve non-duality in both languages. This will be expressed in my website and book. It's a journey. 
In other words, my value is to teach language and non-duality in fun, creative, and easy to learn ways.

In an effort to form deeper connections, my new gf and I tried a “soul gazing” exercise. The couple simply sits face to face on meditation cushions and gazes directly in each other’s eyes. The guide suggested only 5min. for first- timers and to just be aware of any uncomfortable thoughts/feelings that may arise. . . I had never tried this with a gf and was curious. She is buddhist and has sporadically meditated, so I thought we might connect.
I felt comfortable and had interest/desire in gazing into her eyes. She immediately became uncomfortable. She asked if we could hold hands. She couldn’t maintain eye contact for more than a few seconds. She kept closing her eyes and sighing. After a few minutes, she said five minutes must have passed and asked if we should check the timer. A minute later she stood up to check the timer. It went off just as she checked it. She looked discouraged and apologized. I told her it was fine and everything went just like it was supposed to.
I found her behavior interesting. I don’t think it was due to overtly hiding something (like seeing another guy). She seems transparent and it was her idea to do the soul gazing.
Perhaps consistent eye contact is intensely intimate for some. Perhaps there are deeper insecurities. I thought it also may reflect a low level of self love. I wonder if it was something she saw in me or something she felt was being seen. Or perhaps resistance to becoming one and losing herself.
