There is a very important thing to know when we communicate with discarnate beings. As we know, there are two hierarchies of discarnate beings - the one belonging to the Divine family of spirits, and the one of rebellious spirits that disconnected themselves from the Divine. The key feature of the Divine spirits are the unity with the Divine and sharing the key Divine attributes of Love, Compassion, Beauty and Oneness. The key features of the rebellious spirits are the sense of separate self-identity, disconnectedness from the Divine Self, sense of pride and arrogance, inability to feel love and compassion. Yet, they are still very knowledgeable about all the structures and mechanics of the Spheres and the laws of the World in the astral and material realms. They also watch us and know all our entanglements and the history of our previous lives. Remember that Lucifer was a Seraphim and still has all the knowledge available to the spirits of such high hierarchy. Apparently, knowledge by itself is useless if it is not accompanied with the direct connectedness with the Divine and its Love.
Gospels gave us clear warnings when dealing with discarnate spirits:
And what are the signs that we are progressing towards the Divine on our spiritual path? And on the same token, these are the signs of communicating with the spirits of the Divine hierarchy. Again, Gospels give us clear signs:Beloved, do not believe every spirit, but test the spirits to see whether they are of God (1 John 4)
And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants also masquerade as servants of righteousness. (2 Corinthians 11:14)
"For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places." (Ephesians 6:1)
So, there is a reason we are veiled from the knowledge of the world structures on higher levels while in the human body. The lesson here for us to learn is not to gain the knowledge of structures and speres, but to return to the oneness with the Divine Self and learn to Love.If I speak in human and angelic tongues but do not have love, I am a resounding gong or a clashing cymbal. And if I have the gift of prophecy and comprehend all mysteries and all knowledge; if I have all faith so as to move mountains, but do not have love, I am nothing.
(1 Corinthians 13:2)
The fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. (Galatians 5:22)
"I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one:I in them and you in me. May they be brought to complete unity to let the world know that you sent me and have loved them even as you have loved me. I have made you known to them, and will continue to make you known in order that the love you have for me may be in them and that I myself may be in them." (John 17)
“A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.” (John 13)
And so, when we communicate with discarnate beings, there is a key criterion to discern which hierarchy they belong to. I know this for a fact because I communicated with a Divine spiritual being, and that was an experience of complete melt into the Light and unconditional Love so overwhelming that there is nothing in human words to describe it. However, if we communicate with a discarnate being and gain some esoteric knowledge, and yet, do not sense the Divine Love and Oneness, and after such communication we feel more prideful of ourselves because of our knowledge and arrogant towards those who do not have this knowledge, if as a result of our practice and communications with the spirits we do not find in ourselves “The fruit of the Spirit - love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control.”, then this is a clear sign that we are talking to a wrong hierarchy. They also often masquerade as benevolent beings emanating light, and in this light you may feel very elevated and awesome, but this light is cold and there is no sense of unconditional love and oneness with the Divine.For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. (1 Corinthians 13:12)
It is not for you to know times or seasons that the Father has fixed by his own authority. (Acts 1:7)
For with much wisdom comes much sorrow; the more knowledge, the more grief. (Ecclesiastes 1:18)
Also it is worth noting that Buddha also taught about non-importance of any knowledge that is not directly related to the awakening to our Divine nature:
Once the Blessed One was staying at Kosambi in the simsapa[1] forest. Then, picking up a few simsapa leaves with his hand, he asked the monks, "What do you think, monks: Which are more numerous, the few simsapa leaves in my hand or those overhead in the simsapa forest?"
"The leaves in the hand of the Blessed One are few in number, lord. Those overhead in the simsapa forest are more numerous."
"In the same way, monks, those things that I have known with direct knowledge but have not taught are far more numerous [than what I have taught]. And why haven't I taught them? Because they are not connected with the goal, do not relate to the rudiments of the holy life, and do not lead to disenchantment, to dispassion, to cessation, to calm, to direct knowledge, to self-awakening, to Unbinding. That is why I have not taught them.
