I have watched part of this.
What I notice is how far this departs from anything taught in the Bible. Where does one get the 'revelation' that the silver cord is something that can connect an astral projector to one's body?
The silver cord
Ecclesiastes 12:5 Also when they shall be afraid of that which is high, and fears shall be in the way, and the almond tree shall flourish, and the grasshopper shall be a burden, and desire shall fail: because man goeth to his long home, and the mourners go about the streets: 6 Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern.
Commentaries on Ecclesiastes 12:6 generally interpret the verse as a metaphorical description of old age and the approach of death, using imagery of a life-sustaining water-drawing apparatus falling into disrepair. The "silver cord" is often understood as the spinal cord or nervous system, the "golden bowl" as the brain, and the "pitcher" and "wheel" as the vital functions and organs of the body, all of which are ultimately broken and cease to function at death.
For the silver cord to be loosed indicates death, just as the golden bowl being broken would also indicate death. The wheel sounds like the function of the heart.
Matthew 13:5 But while men slept, his enemy came and sowed tares among the wheat, and went his way.
This verse indicates that Satan and his minions can come while you sleep and sow tares. The interpretation is that during sleep we are susceptible to this and they can sow tares in our dreams. You can pray before you go to sleep that God give you rest and that God give you peace in your sleep.
Psalm 129:4 The Lord is righteous: he hath cut asunder the cords of the wicked.
In Ecclesiastes we understand the silver cord to refer to their life, the cord connecting the body to the spirit. But that would not make sense that God has cut asunder the cords of the wicked simply referring to death since everyone dies. To be wicked indicates you are doing something that is wicked. To cut the cord indicates that you lose control over whatever wicked thing you are doing. We know from Matthew that one of the wicked things they do is to sow tares in your dreams during your sleep.
Psalm 140:5 The proud have hid a snare for me, and cords; they have spread a net by the wayside; they have set gins for me. Selah.
This proves that the proud are hiding cords to bind you. So it can't refer to their life, it could refer to binding you with the cords of sin.
Proverbs 5:22 His own iniquities shall take the wicked himself, and he shall be holden with the cords of his sins.
Isaiah 5:18 Woe unto them that draw iniquity with cords of vanity, and sin as it were with a cart rope:
Clearly evil people draw iniquity with cords of vanity. If they are trying to draw a Christian to commit iniquity they are drawing you with cords of vanity, it makes sense to pray that those cords would be cut.
The term "the silver cord" is only used once in the Bible and clearly refers to a cord connecting the Body to the Spirit and thus to life. The idea is that if a spirit leaves the body it is still connected by the silver cord which is why we have NDE and people being caught up to heaven to have visions, and perhaps also by the occult in sowing tares in peoples dreams while they sleep.
