Class 9 - Hindi - गीत-अगीत - कविता का सारांश (#CBSEClass9Notes)

गीत-अगीत

रामधारी सिंह ‘दिनकर’ (१९०८-१९७४)

कविता

गीत, अगीत, कौन सुंदर है?

गाकर गीत विरह की तटिनी

वेगवती बहती जाती है,

दिल हलका कर लेने को

उपलों से कुछ कहती जाती है।

तट पर एक गुलाब सोचता,

"देते स्‍वर यदि मुझे विधाता,

अपने पतझर के सपनों का

मैं भी जग को गीत सुनाता।"

गा-गाकर बह रही निर्झरी,

पाटल मूक खड़ा तट पर है।

गीत, अगीत, कौन सुंदर है?

बैठा शुक उस घनी डाल पर

जो खोंते पर छाया देती।

पंख फुला नीचे खोंते में

शुकी बैठ अंडे है सेती।

गाता शुक जब किरण वसंती

छूती अंग पर्ण से छनकर।

किंतु, शुकी के गीत उमड़कर

रह जाते स्‍नेह में सनकर।
