How to have sukham?

[soundararajan50]

लोभ-मूलानि पापानि, रस-मूलानि व्याधयः ।
इष्ट-मूलानि शोकानि, त्रीणित्यक्त्वा सुखी भव ॥

lobha-mūlāni pāpāni, rasa-mūlāni vyādhayaḥ ।
iṣṭa-mūlāni śokāni, trīṇi tyaktvā sukhī bhava ॥

sins have root in greed, diseases have root in taste.
sorrows have root in desire, leave the three and be happy
