All creation that you see emanates from the Lord. That the great variety that we see around us is coming only as a result of the change in our own qualities (Gunas) is a truth that is asserted by the sacred texts. You are sometimes very happy, sometimes afraid, and at other times courageous. These changes come about in quick succession and in a casual way. The main reason for all these changes is the change that comes in our own mental attitude. These are manifestations of one’s own qualities. Man has three distinct qualities or gunas - satwa, tamo, and rajo gunas. If these are mixed in a balanced manner, there will be no drastic change in one’s nature. Sunlight is composed of seven different colours. When these colours are mixed in appropriate proportions, there will be no change, and the Sun will shine in its natural colour. On the other hand, if there is an imbalance in the manner in which these colours are mixed, then you will find that some special colours show themselves.( Summer Roses on Blue Mountains, 1976, Ch 9.)
