Jahangir after his recovery told Hari Dass to release Guru Hargobind Ji. But the Guru refused to leave the fort without the Hindu Princes.
Unwilling to release the Princes, but due to Guru's obligation, he kept a clever condition, that "whoever can hold on to the Guru's cloak can be released." The Guru with his heart full of compassion for the plight of others was determined to get the prisoners freed.
He had a cloak made with 52 corners or tails. So, as the Guru walked out of the gate of the fort the fifty-two princes trailed behind, each holding on to his own tail of the Guru's special cloak. The Guru's cleverness had trumped Jahangir's clever condition and liberated the fifty-two princes. Guru Hargobind is therefore also known as Bandi-Chhor (Liberator).
Guru Hargobind Singh Ji's return to the holy city of Amritsar was celebrated by his followers by lighting up the entire city. After almost four hundred years this tradition continues in Amritsar, and on this day the Harmandir Sahib is aglow with thousands of candles and floating lamps, strings of lights decorate the domes, and fireworks burst in the sky.
