The place where the MIND and INTELLECT act together is the INNER CONSCIENCE. This is the true wealth of every person as it is the antahkarana that bestows complete strength & power upon man!
If we want to rise against injustice, then we must first become strong & powerful by mind, body and intellect.
The best form of relaxation for the mind is to keep it at peace & focussed and to dwell on thoughts which foster a sense of Purity & Happiness.
