According to the mythological account, Jara, as an incarnation of Viswakarma, shot an arrow at Lord Krishna's foot, which was the only mortal part of his body.

According to the mythological account, Jara, as an incarnation of Viswakarma, shot an arrow at Lord Krishna's foot, which was the only mortal part of his body.

This arrow was said to be made of a blade of grass that had been infused with the power of the divine architect Viswakarma.

The arrow pierced Krishna's foot, causing his physical body to perish. However, his divine spirit escaped and returned to his heavenly abode.

So, in essence, Jara's action was not an ordinary act of violence but rather a divine intervention that facilitated Krishna's transition from his earthly incarnation to his divine form.

After Jara shot the arrow that killed Lord Krishna, the divine energy that had been sustaining the Yadava dynasty began to wane.

According to the Mahabharata, the Yadavas, who were Krishna's kin, began to fight among themselves and eventually destroyed each other.

The city of Dwaraka, which was the capital of the Yadavas, was also submerged in the sea, marking the end of the Dwapara Yuga and the beginning of the Kali Yuga.

Jara, having fulfilled his role in the divine plan, is said to have disappeared from the scene, his mission accomplished.

After the event of Lord Krishna's passing, the Viswakarma community, to which Jara belonged, is said to have faced a curse.

According to legend, Lord Krishna's devotees were so grief-stricken by his passing that they cursed the Viswakarma community, saying that they would never again be able to practice their traditional crafts and skills with the same level of excellence.

As a result, the Viswakarma community is said to have wandered the earth, seeking redemption and a way to lift the curse.

However, it's worth noting that this story may be more of a mythological explanation for the decline of the Viswakarma community's traditional skills, rather than an actual historical event.
