In 1700, Guru Gobind Singh Ji sent out Hukamnaame (commands) to the Khalsa Panth (collective of initiated Sikhs) to come Tyar Bar Tyar (ready upon ready) to Anandpur Sahib to celebrate the first Holla Mahalla, after the righteous festival of Holi had taken a different path. Guru Gobind Singh Ji themselves got the Khalsa to practice and re-enact battles. There the Khalsa physically trained and prepared for the Jangs (battles) that were yet to come.
Holla Mahalla for us today is a reminder to be Tyar Bar Tyar (ready upon ready), both physically and spiritually. May it be a time of inspiration for us to progress on our journeys towards becoming both a Sant (saint) and a Sipahi (soldier). Holla Mahalla is still celebrated every year at Anandpur Sahib and many other places around the world.
