Jainism is an ancient Indian religion that emphasizes non-violence, self-control, and asceticism as paths to spiritual purity and enlightenment. Its fundamental principles are articulated through the teachings of twenty-four Tirthankaras, who are considered spiritual teachers and propagators of the Dharma.

Jainism: Core Principles and Vows

The core of Jain philosophy revolves around the idea that every living being has a soul, and the goal of life is to achieve liberation (moksha) from the cycle of rebirth through ethical living and self-discipline. This is primarily achieved by observing certain vows that guide one's conduct.

Parswanatha's Four Vows Explained

Tirthankar Parswanatha, the 23rd Tirthankar in Jainism, laid down four fundamental vows for his followers. These vows were considered essential for a life of spiritual purity and are known as the 'Chaturyama Dharma' (Four-fold Religion). They include:

• Non-injury (Ahimsa): This is the most paramount principle in Jainism, advocating for complete non-violence towards all living beings, including humans, animals, and even microscopic organisms.
• Truthfulness (Satya): This vow dictates that one must always speak the truth and only that which is pleasant and beneficial. Harsh or harmful truths should be avoided.
• Non-stealing (Asteya): This means not taking anything that has not been given willingly. It extends beyond physical theft to include not taking advantage of others or illicit gains.
• Non-possession (Aparigraha): This vow emphasizes limiting one's worldly possessions and desires. It encourages detachment from material wealth and comforts to prevent greed and attachment.

Mahavira's Addition: Celibacy and the Five Mahavratas

Vardhaman Mahavira, the 24th and last Tirthankar of Jainism, played a crucial role in systematizing and expanding the existing teachings. While he reaffirmed the four vows taught by Parswanatha, he added a fifth vow, making the path to spiritual liberation more rigorous, especially for monks and nuns. The concept he added was Celibacy (Brahmacharya).

Mahavira emphasized a stricter observance of all vows, and he made celibacy mandatory for ascetics, believing it was essential for complete self-control and the renunciation of worldly pleasures, which is vital for achieving moksha.

Understanding the Five Great Vows (Mahavratas)

With Mahavira's addition, the four vows of Parswanatha became five, collectively known as the 'Pancha Mahavratas' or the Five Great Vows. These vows are observed with great strictness by Jain monks and nuns and to a lesser degree by Jain laypersons (Anuvratas). The five Mahavratas are:

Therefore, among the given options, Celibacy was the specific concept that Vardhaman Mahavira added to the existing teachings of Jain Tirthankar Parswanatha, strengthening the ascetic discipline in Jainism.
