3. He was incredibly compassionate:
Swami Vivekananda represented India and Hinduism in the Parliament of World religion, in Chicago, and before going abroad, he was tested by his mother on whether he had the right to preach Hinduism. After a delicious supper, both of them sat down to eat some fruits. Swami cut the fruit, ate it and after that, his mother asked him for the knife; he handed over the knife to his mother and she was more than pleased. She said 'you have passed the test and you are now eligible to preach the world,' a confused Swami questioned her what was she talking about?
His mother replied, "Son, when I asked for the knife, I saw how you handed it to me, you gave the knife by holding its sharp edge and kept the wooden handle of knife towards me; so that I would not get hurt when I take it and this means you took care of me. And this was your test in which you passed."
To have compassion and being able to take good care of others is a remarkable quality, it is the law of the nature that the more selfless you are the more you will receive; and so did Swami Vivekananda.
