The Great Epic of the Bhārata dynasty 5.33.46

5.33.46

ekamevādvitīyaṃ tadyadrājannāvabudhyase |
satyaṃ svargasya sopānaṃ pārāvārasya nauriva || 46 ||

When a bowman shooteth an arrow, he may or may not succeed in slaying even a single person, but when an intelligent individual applieth his intelligence (viciously); it may destroy an entire kingdom with the king. Discriminating the two by means of the one, bring under thy subjection the three by means of four, and also conquering the five and knowing the six, and abstaining from the seven, be happy. Poison slayeth but one person, and a weapon also but one; wicked counsels, however, destroy an entire kingdom with king and subject. Alone one should not partake of any savoury viand, nor alone reflect on concerns of profit, nor alone go upon a journey, nor alone remain awake among sleeping companions. That Being who is One without a second, and whom, O king, thou hast not been able to comprehend, is Truth's self, and the Way to heaven, even like a boat in the ocean. There is one only defect in forgiving persons, and not another; that defect is that people take a forgiving person to be weak. That defect, however, should not be taken into consideration, for forgiveness is a great power. Forgiveness is a virtue of the weak, and an ornament of the strong. Forgiveness subdueth (all) in this world; what is there that forgiveness cannot achieve? What can a wicked person do unto him who carrieth the sabre of forgiveness in his hand? Fire falling on a grassless ground is extinguished of itself. And unforgiving individual defileth himself with many enormities.
