Identify claudius claim about hamlet 's mourning ?

Claudius claims Hamlet is "unmanly" for his prolonged sadness over the death of his father. He says that it is virtuous to feel sad hor his father's passing but most stubborn and incorrect to God to obsess over it. Claudius explains that everybody must, sooner or later, lose a father.

But you must know your father lost a father,
That father lost, lost his, and the survivor bound
In filial obligation for some term

To do obsequious sorrow. But to persever
In obstinate condolement is a course
Of impious stubbornness. 'Tis unmanly grief.
It shows a will most incorrect to heaven,
