Is it really valid to equate the individual mind with service-to-self? Sure. Because even if I use my individual mind to serve others it's still MY interest that is being served. So it's actually always service-to-self when we operate from the individual mind.
And is service-to-others only possible with a collective mind? Yes. Only when our minds unite into a harmonious whole can we truly serve one another.
