When another honors you enough to share a win that they’ve experienced, reinforce that win immediately and with no question! To withhold encouragement deliberately, is to display an egoistic mentality.
Reveling in another’s victory doesn’t cost the soul a dime! On the contrary, souls exist to love, to recognize others, and to elevate other souls!
The False-Self, on the other hand, is quite the anal accountant when it comes to these sorts of things. Tit for Tat, and continually concerned that other egos should not be too inflated, relative to their own!
