What ever reason, what ever one might feel right in his ways or wrongly treated: A Dhammika advices to abstain from wrong doing, reminds that letting go leads to peace. Gives comment-less what's needed: dwelling, food, medicine, cloth. A wise person does not take side, does not give any anchors that conceit and heat can grow, either on this or on the other side. A wise person reminds on the root thinking which leads upward and beyond and remembers that to take on it is nothing one should demand from others but ones own goodness and liberating way:
"And how is one made pure in three ways by mental action? There is the case where a certain person is not covetous. He does not covet the belongings of others, thinking, 'O, that what belongs to others would be mine!' He bears no ill will and is not corrupt in the resolves of his heart. [He thinks,] 'May these beings be free from animosity, free from oppression, free from trouble, and may they look after themselves with ease!' He has right view and is not warped in the way he sees things: 'There is what is given, what is offered, what is sacrificed. There are fruits & results of good & bad actions. There is this world & the next world. There is mother & father. There are spontaneously reborn beings; there are brahmans & contemplatives who, faring rightly & practicing rightly, proclaim this world & the next after having directly known & realized it for themselves.' This is how one is made pure in three ways by mental action."
While the fools take side, even provide means for killing each other for their own sake, gains, impure and defiled, the wise person, having not only done his duties in this way, but acted like a Brahma, takes then leave, renounces in the forest, becomes even one never to return again in this world, letting the world burn in accordance to beings own kamma.
Saying so, it's time to leave the slaves of their desires, unwilling for any skilful efforts, here behind with this gift of Dhamma, providing with deathlessness.
