Yes, as I recently commented on a story: "With regard to manifestation, the new age spirituality concept that we can all manifest our desires through positive thoughts and energy is claptrap used to sell books to the masses who eat up spiritual materialism--an unfortunate side effect of the foibles of capitalism and confirmation bias. What everyone does have the power to manifest is contentment and serenity by altering our reactions and attitudes."
Regarding karma, I've come to believe in a simple definition that falls outside of any religious/philosophical teaching: "Karma is a vibrational level that draws the experiences needed for healing and growth to a soul. Nothing more." And building off that, I redefined the LoA to be the vibrational pulls of our soul contracts, https://medium.com/channspirations/revisiting-karma-and-the-law-of-attraction-997965601b65 which I prefer to call improv scripts to account for free will.
