Haven't read this thread or the thread linked by OP yet so sorry if this is redundant, but if things are as OP has stated and a consensus has been formed that learning to "embody love" is the way forward (I believe it is, personally), I feel I must post.
Over the last couple years I haphazardly stumbled upon a way of tapping into an infinite source of absolute love that is always available to everyone. Being an extremely lonely user for most of my life, going through painful relationships that left me even more lonely, and then spending the last several years in a pretty extreme state of isolation, eventually my loneliness (a feeling that I believe is actually your soul being starved for love) became so debilitating and overwhelming that I had to do face it directly and deal with it if I was ever going to make any progress on anything in life again. My relationships and other events in my life had long since convinced me that finding a source of love through relationships with other people was no real solution at all. People are unique and ever changing making any true bond of love extremely difficult to find or form, and ultimately, even if you manage to form such a bond, people die, and when your bonds are inevitably broken, you will be left even more starved for love than you were before. All external remedies are only temporary bandaids on the wound. The only true lasting solution is to heal the wound itself.
Sit or lie down, comfortably. Take a moment to relax, whatever that means to you. Progressively stop all effort. Relax your body. When you notice you're still holding some tension somewhere, relax that, and so on, and so on. Soon, the most active part of your existence will be your "mind", probably experienced as internal chatter. Relax out of the chatter. You don't need to shut it down or forcefully stop it, or even stop it at all, that would be to make an effort. What we're doing is achieving absolute rest and the only way to do this is to let go of all effort. As you let go, you'll realize that you are not what you thought you were. You've entirely ceased all bodily effort, and yet the body continues to feel, move internally, breathe, etc., likewise, you've ceased (at least most) mental effort, and yet the mind is still up there spinning out sentences and feelings. You don't need to stop any of this in order to come to absolute rest, because none of it is actually you. You are some core thing deep down inside this machine, and the way for you to rest is to let go and drain down out of the machine, it can keep doing what it will, that's fine, you're resting there, inside.
One of the last things that remains is your will to let go, and once you perceive your own will, in this way, operating below the level of the body, below the level of mental chatter, you are well on your way to finding the state this post is written to help you to find. Now experiencing your own will to let go, you let go of it. "How do I let go of letting go? That doesn't make sense." No it doesn't make logical sense, but once you have a feel for what it is to let go of something, to stop engaging in it, you will be able to feel how you can in fact do this. Just like the body and the mind, you will let go of the will and find that it wasn't the core "you" either. And just like the body and mind it may keep chugging along, willing, as you, whatever you are, relax out of it, sinking deeper inside, drifting further outside, unbounded, like a cloud of mist permeating infinitely inward and outward, everywhere. As you come closer and closer to absolute rest a spontaneous feeling of supreme satisfaction and love will spontaneously well up around and inside you. Immediately you may be drawn back into the mind and body, wanting to analyse this feeling, hold on to it, increase it, etc., but as you continue to engage in this easy practice, and it continues to work, you'll become more and more secure in the knowledge that it will always be there for you no matter what. You don't need to cling onto it, and trying to will only scare it away. But if you let go, come to rest, make peace with whatever arises in your awareness and let it go, that deep, indescribable love will always be there for you again.
It's easy and you can learn to do it in a few sessions. More practice won't help or hinder you in finding the state this post is about. It's only a matter of really (not) doing it. really stopping everything. Really letting it all go. If you really decide to do it, you can discover it on your first (non)try. This is the most important thing I've discovered in my life and I know you can do it too. It's easy.
