Did you know fireworks existed during the times of the Gurus? Guru Gobind Singh (1666-1708) when writing about the love the Gopis had for Krishna uses it in a metaphor for the flash of light, like fireworks in the dark of night, which was experienced when these love-sick women saw their beloved Krishna. ਤਿਨ ਗ੍ਵਾਰਿਨ ਕੋ ਅਤਿ ਹੀ ਪਿਖਿ ਪ੍ਰੇਮ ਤਬੈ ਪ੍ਰਗਟੇ ਭਗਵਾਨ ਸਿਤਾਬੀ ॥ Seeing the intense love the Gopis had, Bhagwan (Krishna) then quickly appeared before them ਜੋਤਿ ਭਈ ਧਰਨੀ ਪਰ ਇਉ ਰਜਨੀ ਮਹਿ ਛੂਟਤ ਜਿਉ ਮਹਤਾਬੀ ॥ It appeared like such a flash of light upon the earth, as if fireworks going off in the dark of night [[Dasam Guru Granth Sahib/Dasam]] pg 343 This particular type of firework mentioned above by Guru Gobind Singh, mehtābī ਮਹਤਾਬੀ, was a kind of firework which has an illumination like the moon, somewhat light blue, producing a burst of glittering sparks which fan out in a cascading pattern. Sikh historical texts also mention fireworks (ਆਤਿਸ਼ਬਾਜ਼ੀ) as part of the celebrations at the weddings of the Gurus and on festivals like Diwali.
