The Khanda symbol can be seen on the walls, windows etc. of the Bangla Sahib Gurudwara. The symbol derives its name from the double-edged sword (also called a Khanda) which appears at the center of the logo. It is the military emblem of the Sikhs. The importance of this symbol is explained in one of the displays in the museum inside the Gurudwara complex. According to
which the emblem is composed of four different components. These components are:
1. Khanda: This double-edged sword is a metaphor of Divine Knowledge, its sharp edges cleaving Truth from Falsehood. The AMRIT which is used at the time of BAPTISM is stirred with the Khanda.
2&3. Kirpan of Miri and Piri: Two swords arranged in a cross like manner is called as kirpan of Miri(2)and Piri(3). The story behind the swords is- after the execution of Guru Arjan at the hands of Jahangir, Guru Har govind clearly saw that it would no longer be possible to protect the Sikh community without the aid of arms hence he wore the two swords. The word miri has been derived from Persian word “miri”, which literary means commander, governor, etc, and signifies temporal power or material control. The word piri has been derived from Persian word “pir” literary meaning saint, spiritual guide, and stands for spiritual authority or control over the soul of the person(Singha,2005).
4. Chakar: The circle in the middle represent eternity as it has no end or beginning.
