Gosala Maskariputra was associated with the Ajivikas sect. The Ajivikas were an ancient Indian sect that emerged around the same time as Buddhism and Jainism. They were known for their ascetic practices and belief in determinism, a philosophy that claimed that all events and actions were predetermined and that human beings had no free will.

The Ajivikas were founded by Makkhali Gosala, also known as Gosala Maskariputra, who was a contemporary of Gautama Buddha. Gosala was a Jain monk who later broke away from Jainism and founded his own sect. He believed in the concept of Niyati, which stated that all living beings were bound by fate and could not alter their destiny.

While the Ajivikas were known for their strict asceticism and belief in determinism, their influence gradually declined over time. Today, the Ajivikas sect is considered to be extinct, with very few traces of their teachings and practices remaining.

In conclusion, Gosala Maskariputra was associated with the Ajivikas sect, an ancient Indian sect known for their ascetic practices and belief in determinism.
