Lyrics of "Jana Gana Mana" in Hindi (जन गण मन):-
============================================================================================

जनगणमन अधिनायक जय हे, भारतभाग्यविधाता।
पंजाब सिंध गुजरात मराठा, द्राविड़ उत्कल बंग।
विंध्य हिमाचल यमुना गंगा, उच्छल जलधि तरंग।
तव शुभ नामे जागे, तव शुभ आशिष मागे।
गाहे तव जयगाथा।
जनगणमंगलदायक जय हे, भारतभाग्यविधाता।
जय हे, जय हे, जय हे, जय जय जय जय हे॥

Lyrics of "Jana Gana Mana" in Bengali (জন গণ মন):-

জনগণমন-অধিনায়ক জয় হে ভারতভাগ্যবিধাতা!
পঞ্জাব সিন্ধু গুজরাট মরাঠা দ্রাবিড় উৎকল বঙ্গ
বিন্ধ্য হিমাচল যমুনা গঙ্গা উচ্ছলজলধিতরঙ্গ
তব শুভ নামে জাগে, তব শুভ আশিষ মাগে,
গাহে তব জয়গাথা।
জনগণমঙ্গলদায়ক জয় হে ভারতভাগ্যবিধাতা!
জয় হে, জয় হে, জয় হে, জয় জয় জয় জয় হে॥
