Ajivika is a deterministic philosophy that places a strong emphasis on the concept of fate. This ancient Indian school of thought believes that everything in the universe is predetermined and that individuals have no control over their own lives. In this belief system, fate is seen as an all-encompassing force that dictates the course of one's life, from birth to death.

In terms of rituals and practices, Ajivika does not have any specific or prescribed rituals. This is because the philosophy holds that everything is predetermined, including one's actions and choices. Therefore, performing any rituals or practices would be seen as futile and meaningless.

However, there are certain practices that can be associated with Ajivika, such as meditation and asceticism. These practices are not seen as a means to change one's fate, but rather as a way to detach oneself from the material world and achieve a state of enlightenment. This is in line with the belief that one's fate is predetermined and cannot be changed, but by detaching oneself from worldly desires, one can achieve a sense of inner peace and understanding.

Meditation is seen as a way to calm the mind and detach from the physical world, allowing one to focus on the present moment and accept one's predetermined fate. Asceticism, on the other hand, involves giving up material possessions and living a simple and austere lifestyle. This is seen as a way to detach from worldly desires and focus on spiritual growth.

Another practice associated with Ajivika is the acceptance of one's fate. This philosophy teaches that everything that happens in one's life is a result of fate, and it is futile to resist or fight against it. Therefore, individuals who follow Ajivika often strive to accept their fate and find peace and contentment in it.

In conclusion, while Ajivika does not have any specific rituals or practices, there are certain practices that can be associated with this deterministic philosophy. These practices are focused on achieving a sense of detachment from the material world and accepting one's predetermined fate. Whether one believes in the concept of fate or not, these practices can serve as a means to achieve inner peace and contentment.
