Sri Aurobindo
Letters of Sri Aurobindo
Volume IV - Part 2
I think no rule can be laid down applicable to all. There are some who have the expansive tendency of the vital, others who have the concentrative. The latter are absorbed in their own intensity of endeavour and certainly they gather from that a great force for progress and are saved the expense and loss of energy which frequently comes to the more communicative and also make themselves less open to reactions from others (though this cannot be altogether avoided). The others need to communicate what is in them and cannot wait for the full fullness before they use what they have. Even they may need to give out as well as to take in in order to progress. The only thing is that they must balance the two tendencies, concentrating to receive from above as much or more than they open sideways to distribute.
