The concept of Anuvrata was advocated by Jainism.

Explanation:
Anuvrata is a concept that was introduced by Jainism, a religion that originated in ancient India. It is an ethical code of conduct that promotes the idea of practicing non-violence, truthfulness, non-stealing, celibacy, and non-possession in everyday life. Anuvrata is derived from the word "anu" which means "small" or "little," and "vrata" which means "vow" or "observance." Therefore, Anuvrata can be understood as a set of small vows or observances that individuals can adopt in order to lead a disciplined and virtuous life.

Key Points:
- Anuvrata is a concept that is often contrasted with the concept of Mahavrata, which refers to the major vows taken by Jain monks and nuns who renounce the material world completely.
- While Mahavrata is only practiced by the Jain monastic community, Anuvrata is meant for laypeople who continue to live in society.
- Anuvrata encourages individuals to incorporate certain principles and practices into their daily lives, without completely renouncing worldly responsibilities.
- The five principles of Anuvrata are:
1. Ahimsa (non-violence): This principle emphasizes the avoidance of physical, mental, and verbal harm to all living beings.
2. Satya (truthfulness): Practicing truthfulness in thoughts, words, and actions is essential in leading an ethical life.
3. Asteya (non-stealing): This principle promotes honesty and integrity, discouraging the act of stealing or taking what is not rightfully ours.
4. Brahmacharya (celibacy): This principle encourages individuals to practice self-control and moderation in their sexual desires.
5. Aparigraha (non-possession): The principle of non-possessiveness teaches individuals to limit their desires and attachment to material possessions.

- Anuvrata is seen as a practical way for laypeople to cultivate virtues and reduce negative karma, which is believed to be the cause of suffering and rebirth in Jainism.
- By following the principles of Anuvrata, individuals can strive for personal growth, moral development, and contribute positively to society.

In conclusion, the concept of Anuvrata was advocated by Jainism as a way for laypeople to lead an ethical and virtuous life by adopting the principles of non-violence, truthfulness, non-stealing, celibacy, and non-possession. This concept encourages individuals to practice self-discipline and cultivate virtues in their everyday lives.
