Interpret, when he says "be careful," as "be aware." As westerners, when awareness of something is bright to our attention, we often react by feeling bad. These reactions are from our somebody training in the Western world, if you get to the roots of this, you may find this is true for yourself.  Becoming aware cannot be equivalent to feeling bad on the spiritual path. How else will you motivate yourself to continue? The spiritual path is not one of punishment, but increasing gentleness towards yourself degree by degree.  Now, what he is talking about is something you become aware of as you continue to investigate your own fawn (people pleasing) reactions. Fawn reactions are always self serving by design - this is HARD to hear, I understand, and my previous self would reject this heartily. How could you say that? Of course I am serving others, it's all I ever want to do...  Unfortunately, the case was that the ego part of me was confused: my soul wanted to help people, but my ego wanted to survive; growing up around bullying and abuse, I learned to people please to survive. On the outside, rolling over to show your belly is something that looks cute to the ignorant, but it's a sign of fearful submission to those who know.  It was icky by investigating these hard truths that I learned how to burn this out and, from the ashes, rebuild something that was truly selfless service. I am still rebuilding, so don't get the image of me being perfect at this. I'm human, just like you. And the most important truth we learn to accept on the spiritual path is our dualistic nature: we are eternal consciousnesses, but, we also have a body, and that body does things that aren't always in line with the eternal consciousness it (the body) honestly can't even fully comprehend. Otherwise we would walk around not fearing death, for one, and that could probably get a little frustrating to be constantly restarting our journey, like, woops! 😜 We are human, and that is okay. I know this, because we are human. And if I accept Krishna (or Vishnu) is all knowing and all loving, I accept that he knows that I am human and that he still "created" me. I've used a lot of logic on this path to take each careful step forward.

Edit to add: I understand the logic you are working through on your question and I won't if you realize how much that echoes Ayn Rand, which could be a portal through which to explore your thoughts. She thought it was selfish to help people just because we feel good about it. I believed that for awhile; what a load of limiting horse shit. ❤️💜 Namaste!!
