Eid is the main religious festival of the Muslims in Bangladesh.

Eid holds significant importance as the primary religious celebration for Muslims in Bangladesh. It is universally understood to symbolize happiness and joy, which people eagerly share with their family, friends, and loved ones. During this festive period, many individuals living away from home feel a strong urge to return, driven by a deep desire to reconnect with their 'roots' – their families, birthplace, and cultural traditions, as described in the passage. This homecoming reinforces bonds and identity, making Eid a time for unity and belonging.

During Eid vacation, people primarily return to their homes to be with their family, in-laws, and friends. Many individuals who live away from home for various reasons have a strong desire to share the happiness of Eid with their loved ones. This often leads to a significant rush to board different modes of transport like buses, trains, or launches to reach their hometowns, reinforcing their connection to their roots and identity.

According to the passage, our roots refer to the fundamental elements that create a deep bond and provide us with identity. These invisible roots lie in our minds and connect us to various aspects of our lives.

More specifically, our families, our land of birth, relatives, our culture, traditions, and surroundings are considered our roots. These are the elements that develop our identity and make us who we are. When this bond is lost, people feel rootless, lacking identity and feeling empty or lost, as they don't know their origin or direction.

A mad rush is found in the transport sector primarily during religious festivals like Eid because people have a strong desire to return home and share happiness with their near and dear ones. Many individuals live outside their hometowns for various reasons such as work or study, and they eagerly await these holidays to reconnect with their families, in-laws, and friends. This overwhelming urge to 'return to their roots' compels them to board buses, trains, or launches, often leading to overcrowding and a frantic scramble for available transport.
