There is a mindset that involves freeing oneself from
human cultural constructs such as good and evil .
The dark entities I've encountered are more in the realm of parasitic in nature. Nature is neither good nor evil it just is.
Ocean waves are not deliberately setting out to kill us .
If we are killed by natural process that's just natural process .
Belief systems are our worst enemies. In my years of journeying and encounters with many kinds of entities judgement based on cultural conditioning is the most difficult thing to overcome. What we choose to believe about what we experience is the trickiest part of all of this.
On a more nuts and bolts level, yes singing chanting and physical movement when possible can mediate aggressive entity encounters . I'm telling you that mindset is a huge part of all of this going in . That being said in the past I've had the best mindset and setting humanly possible and still have gotten slammed by nasty things. I guess a takeaway from this would be if your going to play in the ocean just know that once in a while a wave will come along and wipe you out regardless.
The good news is that it won't kill you and hopefully it will make you stronger to go deeper next time .

Thank you for this thread. This will definitely change the way I approach my next psychedelic session, particularly with medicinal fungi, which until now, I have approached with a fairly casual, and often last minute mindset. From now on I'd like to treat the substance and journey with more respect in order to open myself up more and gain more from it.
