Q: How can the general atmosphere of humanity affect the Sadhana of the individual or the group?
You see all sorts of things come to you from the universal; that is, from the general atmosphere of humanity — thoughts and ideas in the mind, impulses; etc. in the vital being and so on. It is for this reason that a Sadhaka has to isolate himself from the general atmosphere and create his; own fort where; these things cannot come in easily.
– Sri Aurobindo
