You have often told us that our activities must be an offering to the Divine. What does it mean exactly, and how to do it? For instance, when one plays tennis or basketball, how does one do that as an offering? Mental formations are not enough, naturally!
It means that what you do should not be done with a personal, egoistic aim, for success, for glory, for gain, for material profit or out of vanity, but as a service and an offering, in order to become more conscious of the divine will and to give oneself more entirely to it, until one has made enough progress to know and feel that it is the Divine who acts in you, His force that animates you and His will that supports you – not only a mental knowledge, but the sincerity of a state of consciousness and the power of a living experience.
For that to be possible, all egoistic motives and all egoistic reactions must disappear.
