Boasting is about oneself. Praising is about others.
Boasting puts yourself high. Praising puts the other person high.
Both actions originate from your ownself.
The 1st action reflects your ego, the 2nd one your humility.
In ego you are alone. In humility you feel lost in the crowd, because you have merged with everyone.
Life gives choices, either to seek the massage of your ego, or to seek its destruction. Every single day this choice between ego & its opposite will question you. The answer will lie in which button you press.
A small mind is insecure. To protect itself it needs to boast.
A large heart is secure and filled with love. To further spread love, it spreads positivity by speaking well of and praising others.
Small minds boast, large hearts praise !
