सुभाषितानि

दिवसेनैव तत्कुर्यात् येन रात्रौ सुखं वसेत् ।
यावज्जीवं च तत्कुर्याद् येन प्रेत्य सुखं वसेत् ।।

Sanskrit Subhashit – Subhashitani with hindi meaning

रात्रिमें निश्चिन्तता एवं सुखकी नींद सोने के लिये दिनभर अच्छे कर्म करना आवश्यक होता है। उसी प्रकार जीवनके अन्तमें निश्चिन्तता एवं परम शान्ति की प्राप्ति के लिये जीवन पर्यन्त सत्कर्म करना आवश्यक है।

One should indulge in such deeds during day time by which he gets a comfortable and carefree sleep during the night (without musing over the consequence of his actions during the day). Therefore , so long a person remains alive he should follow this advice and live happily.
