DMT is a huge, monstrous, yet tantalisingly beautyfull octopus creature; Repulsive and attractive at the same time.
A viscious beak, Teeth and nasty poisonous spikes all over it's body and tentacles reaching in every corner of your brain and a scaled skin with SUCH beautyfull colors and designs. It is Male, Female, Disgusting, Delightfull, Kind,
Mercyless, Perfectly ordered, Completely chaotic, Enraged & ultimately peacfull ALL at once.
Ayahyasca is more like a patient, loving grandmother that breaks down one's barriers, like DMT does, yet not so invasive and dominant. It too can become a very stern & sinister spiritual teacher, if it needs to, but, like mushrooms, it much prefers a gentle approach. On the one hand she is calm, positive and loving, but, as any grandmother has, she has a deeply melancholic, slightly bitter side as is typical of a Grandmother that deeply laments seeing her children and Grandchildren misbehave and bring so much suffering onto one another.
Mushrooms are like little, cheery, spiritually teaching, somewhat mischievious elves. They hold up a mirror for
you to see, objectively, yourself clearly. They often hold up the mirror to our hidden sides: Hidden talents & hidden ills. They say "Behold, your own insanity!", yet often they do this with such humour it allows you to laugh at yourself. Sometimes, however, when we are unwilling to face your ills and put up a barrier to them, they become more stern and sinister & even violent in tearing down your barriers, making you see what you need to see. But only if needed. They prefer gentleness.
LSD is like a young, playfull, but troubled philosopher. He finds the most profound bliss in the experience of Life, but at a high price; As high as it can soar is exactly as deep as it can fall into Melancholy & dispair. He is rapidly oscillating between a turbulent, restless & agonised state of being and a Peacefull, blissfull, extatic state of being. This oscillation happens so fast that he cannot decide how he feels at any given moment. Feelings mix that are seemingly contradicting eachother(Melancholy & Extacy, Hope & Dispair, Restlessness & Peace), yet melt together in a confusing mixture where these usually conflicting feelings harmonise and dance, rather than fight with eachother. He is endlessly confused, yet is endowed with such clarity. He cannot define himself and, allthough he accepted this superficially, is still at odds with this on a deep level.
Datura is an old, female, extremely powerfull sorceres. A typical Hag, yet with (at first glance) a soft
maternal energy. It is very attractive. You'll want to lay down in her lap and feel "mothered" and cared for,
yet this is a FATAL mistake, because at any point she can turn into the most murderous, icecold & wrathfull being you've ever seen. When I layed in her lap and she shifted to darkness I was locked and paralysed. Then I saw a spider climbing out of her hood, getting ready to devour me as I lay there helplessly immobilised.
This is actually how I saw Lady Datura in a Dream that followed my rather wreckless & ignorant consumption of her Tea(Brugmansia flowers actually) 2 days prior to that dream. I've prefered to avoid her since then.
New calling perhaps?
