Perhaps we are nickpicking here.  I'm not saying that human love can't have a profound effect on postmortem spirits.  I'm just asking that we acknowledge the complexities of ego-investment and motivation in what we call love and drop the pretention that it can normally be both "pure" and "unconditional."  It is a beautiful thing that almost all parents love their children, but it is not particularly laudatory as a virtue because it is driven by instinct and ego investment.  True, Albert, Jesus and higher beings can project PUL.  I just want us to recognize that true PUL is a fruit of a long developing spiritualty that most never attain, let alone project like water from a fire hose.

Don, it is difficult to describe and put into words what we experience.  You say PUL cannot be "sent" and I agree the word "sent" implies that PUL is propelled, hurled, thrown or launched, and that's not exactly the usual case.  I think a better word is "given" which means to provide, offer, present, furnish, bestow, etc., or even the word "imbue" meaning to instill, fill or permeate.   Any description is prefaced with God as originator, such as God sends/gives/imbues his healing love through me as a means to help another, or carry out God's purpose I think is what is intended by those of us that share our experiences. 

I remember an experience you shared where God imbued you with a powerful energy of indescribable love, so you know it is different in substance than an emotion we may call love.  Physically and emotionally there is clarity, a purity that is tangible and substantial.  Still I think your experience may have been so powerfully compelling that the word "sent" as in propelled, or even thrown into you, your being could be an accurate description.  Of course I wouldn't know since it was your experience.

If a person understands that what some call PUL is the very fundamental essence of creation and our consciousness, because it's a primary attribute of the Creator, then one would likely understand that what we as freewilled (or beings with spiritual will to choose might be more accurate) beings experience are varying levels or degrees of attunement or lack of attunement to PUL.

   PUL is not an emotion, but it can be experienced through emotions and feelings, and that's a very important component of it. One can consider their feeling sense as a primary nonphysical sense that consciousness has always had. It's a sense in the sense that our material senses are senses for the physical reality--a means of perceiving data within same.  Difference is that feeling connects to both nonphysical and physical data/information. With humans, our feeling sense connects to the emotions of the body physical. They are not exactly the same thing, but there is a connection.

  PUL can also be experienced or rather understood in an intellectual/mind or scientific way.  The "Gray ET's" for example, scientifically understand that everything in the Universe and reality is fundamentally interconnected, One, and part of a larger Self and system. They know what you do or don't do to one part of creation, you essentially are doing to yourself. 

  However, due to their history and them trying to get rid of emotion genetically, they lost, or really damped down the feeling experience of Love, and thus became lopsided. 

   Feeling Love is a powerful experience and an impetus to trying to grow more towards clearer and stronger attunement to it at it's finest, more pure, and transcendent expression--true PUL. 

Again, there are degrees of attunement and lack. A lacking metaphor is that there is a powerful electrical energy source at the center of a world, where everyone in the world needs to be connected to for various reasons, but also basic survival.  But each person on that world, has a different transformer within them, based upon the history of their choices. Most of the people are trying to get upgrades, and go to "work" to earn "money" to get upgrades so that they can handle/receive and output, this powerful energy as closer to as is.  One, because it is increasingly and directly pleasurable, but one gains more power to create things, which also is pleasurable. 

   Many humans experience a stepped down version of PUL as in the love of friends, family, and people we connect with based more on material considerations, beliefs, and/or Like attracts and begets Like. 

   True PUL is completely Universal. That is how the Creator experiences Love. If we desire to be consciously One with the Creator, then we must become likewise loving in a Universal manner. No barriers, no separations, no this person or Soul is more deserving of love than this or that person. 

  But these human experiences are but stepping stones for most in the grand scheme of growth. Humanity in a general sense are but children in their understanding, application and expression of, and attunement to PUL. 

  There is both a receptive and expressive side of PUL. There is no really separating these functions as they are but different sides of the same coin of consciousness.  However there is a different feel and experience to the reception and expression of. Both are equally important though. 

   "Sending" PUL then is part of the more expressive aspect of it. Feeling it and opening up to it is part of the more receptive aspect of it.  Note that feeling and opening up to, always comes before the sending, expressive aspect. Yet, it's a feedback loop, because the more you express/direct it outward, the more you feel and can open up to it. Again, two sides of the same coin.   

  This relates to the nature of Yin-Yang, and how Source/the original Creator Consciousness Itself, was first polarized to the Yin (Feminine), then fully integrated It's Yang (Masculine) side and thus became a perfectly balanced/integrated Being which is the ideal state.

  In any case, what PUL is truly, cannot be explained, nor summed up, nor done justice to in any post, nor an entire book, or series of books.  For most, it takes a many, many experiences in various systems and levels, to really truly learn and come to know what PUL is.

  As Like attracts, begets, and resonates with Like--only those whom are closest to PUL within, will more truly and fully perceive and understand what PUL is in a balanced way that involves both the feeling and mental aspects of it. 

  Just as Souls whom are stuck in the hells cannot perceive the expanded dimensions that are much faster vibratory than their level, neither can humans well and accurately perceive PUL unless there is some part of them that resonates with it more than not. The difference between Souls in the nonphysical state and Souls connected to humans in the physical, is that humans and the human experience by nature is the mixed or conglomerate type state where we are working on various different levels and aspects simultaneously, both in an individual and collective sense.

   So even a person whom tends towards the slower vibratory in most ways, may have influencing aspects (from their Disk/Spirt, guidance, etc) that is faster vibratory, and helps to balance out some of the negative/slow vibratory aspects. In this sense, redemption tends to be easier while Souls are focused in this level, than in the nonphysical where Like attracts and begets Like happens in a more pure and immediate way.
