No. It's not easy to let things go, at least most of the time.
I have gotten better at it. And there have been instances in the past when letting go was entirely effortless, but these have been rare, so far.
I keep practicing letting go. I let a great many physical things of property go when I moved to the Philippines to be with the love of my life. That was 4.5 years ago and I haven't hungered to go back. I occasionally hunger for some of the food I used to have, but most of it was killing me. American food industry (+FDA, AMA, American Cancer Society, and others) have betrayed us all.
Asking them to let go of their greed would be difficult, indeed. But the day is fast approaching when it will be ripped from them without their consent. All we can do in the meantime is to help each other overcome some of the damage that has been done.
Change my personality? I've spent a lifetime doing that. It hasn't stopped changing. Studying multiple religions has helped. Scientology counseling has also helped. Reading the Bible continues to help.
We are each spiritual immortals, if we are at least partially awake. It is our duty to awaken fully. Too many, though, are vile mortals who reject their divine true selves within. All they look forward to are the greedy fruit of physical existence, including ego--the source of all evil. (Yep, selfishness is behind every evil act perpetrated. Think about it.)
Perhaps the most striking example of letting go I've ever experienced occurred along with the most striking miracle in my life. Six times, other drivers in rush-hour traffic on Wilshire Boulevard, Los Angeles (1977) assaulted me and my car. And yet, as soon as I realized that I was 100% responsible, the forgiveness was so complete that all attachment to those assaults was forgotten and forgiven. In fact, it took me 33 years to realize that the first people to move out of my way during that miracle were the very ones who helped me realize that miracle.
I suspect that very few people have ever actually forgiven. Too many continue to complain about the hurt and the resentment they continue to suffer.
Only by examining the elements of attachment can one truly find a way to let go. Know the truth and you will be set free. Anything less than truth and the problem (attachment) will persist.
