O sinless one

O sinless Uddhava, in order to understand what is proper in life one must evaluate a given object within its particular category. Thus, in analyzing religious principles one must consider purity and impurity. Similarly, in one’s ordinary dealings one must distinguish between good and bad, and to insure one’s physical survival one must recognize that which is auspicious and inauspicious.
