Everything depends on how you study. You children are making your treasure-stores full of the jewels of knowledge. Only these will be useful to you. You have to imbibe them and become charitable souls. Donate them to others and make them into charitable souls.
Check in the mirror of your heart: To what percentage have I become a charitable soul? How much charity do I perform? People don't understand that donations have to be made and charity performed of the imperishable jewels of knowledge.
