it brings an experience of serenity and peace and a feeling of unity with the One

I think you should perhaps reflect whether your feeling of "unity with the One" is not perhaps self delusion. Your feelings can be mistaken; and how on Earth do you know that other people, with a feeling of unity with their God as sure as yours but an opposite conclusion as to action, can therefore not have had an experience as moving for them as your own?

I'd suggest that people should have the courage to reject such mental aberrations.

It's an abandonment of self or the apotheosis of self esteem?
