Love is the essential glue which keeps the universe from disintegrating. Oneness makes our interactions coherent and internally consistent. The problem is not the ideas themselves, but how they have the potential to manipulate people towards ends which may not have been originally their own. If two or more souls decide to dissolve certain artificial boundaries at various degrees to fulfill whatever common ends they may have, that is their prerogative and can be quite enlightening and beneficial. It is as purifying as drinking water you see, just be careful of the water you drink, it may contain memes which are neither good nor bad in themselves, but could have parasitic effects. Being a 'para'-site isn't inherently bad btw, it depends on the role it plays in the host, they are often essential for various biological functions, absorb the insights which help and release the excess.

"An autotelic person needs few material possessions and little entertainment, comfort, power, or fame because so much of what he or she does is already rewarding. Because such persons experience flow in work, in family life, when interacting with people, when eating, even when alone with nothing to do, they are less dependent on the external rewards that keep others motivated to go on with a life composed of dull and meaningless routines. They are more autonomous and independent because they cannot be as easily manipulated with threats or rewards from the outside. At the same time, they are more involved with everything around them because they are fully immersed in the current of life."
Alexander Technique practitioners tell of experiencing increased autotelic behaviour. They spend time cultivating awareness of the "means-whereby" an activity is performed, rather than focusing on the "end".
