If the inner life of an aspirant is to be harmonious and enlightened, he has to develop and express many divine qualities while he is engaged in his daily duties. Each quality by itself may not seem to be extremely important, but to consider it apart from its necessary relationship with other important qualities is not correct. In  spiritual life all these qualities implement and support each other, and their interconnection is so vital that not one of them can be completely ignored without detriment to many other essential qualities. So, considered in its true function, each of these divine qualities turns out to be absolutely indispensable for a complete life.
