Why Swami Vivekananda asked an Old man to play FootBall!!!

Once an aged gentleman had approached Swami Vivekananda
for his guidance in vedanta and renunciation. Swamiji asked that

person to go and play foot-ball and come back to receive the lessons.

The aged person expressed his inability to do so, because of his old age. 

Then swamiji explained to him that one should learn vedanta, etc., when one is young enough to control the mind, body, senses, etc.,

as it is of no use even if swamiji teaches him at that old age.

the old habits will overtake the mind and it is difficult to control the mind at that age.

"tvayi mayi chaanyatraiko vishnuh
vyartham kupyasi mayyasahishnuh
bhava samachittah sarvatra tvam
vaanchhasyachiraadyaadi vishnutvam..

         bhajare moodamathe!!....."

in you, in me and everywhere there dwells only one, the all-pervading reality,
i.e., vishnu or parabrahma paramaatma. getting impatient and angry with other is
meaningless. giving up all egoistic-feelings of duality completely and maintaining
equal-minded in all circumstances, attain soon the vishnu-status.
