This exquisitely designed commemorative stamp sheet, issued by India Post in 2019, honors the 550th Parkash Guru Purab (birth anniversary) of Sri Guru Nanak Dev Ji, the revered founder of Sikhism. This philatelic masterpiece is a must-have for collectors, history enthusiasts, and devotees alike. The sheet features five distinct and beautifully illustrated postage stamps, each depicting a significant Gurudwara intrinsically linked to Guru Nanak Dev Ji's life journey and spiritual teachings. These include the sacred Gurudwara Nanak Lama Sahib in Chungthang, Gurudwara Darbar Sahib at Dera Baba Nanak in Gurdaspur, Gurudwara Janamasthan in Nankana Sahib (marking his birthplace), Gurudwara Ber Sahib in Sultanpur Lodhi (where he is said to have attained enlightenment), and Gurudwara Nanak Jhira Sahib in Bidar. The central theme prominently displays "550th Parkash Guru Purab" alongside the timeless fundamental principles of Sikhism: "Kirat Karo" (Earn an honest living through hard work and creativity), "Naam Japo" (Meditate on God's name, engaging in spiritual devotion), and "Vand Chhako" (Share and consume together, promoting selfless service and community sharing). Each stamp carries a denomination (1000 or 1500, representing 10 or 15 Indian Rupees respectively), making this not just a collectible, but also a piece of cultural and spiritual heritage. This unique sheet encapsulates the essence of Guru Nanak Dev Ji's philosophy and his profound impact on humanity, offering a tangible connection to Sikh history and traditions. Ideal for display or as a cherished gift, it celebrates a momentous occasion in Sikh faith.
