The question asks us to identify the statement that is not true concerning Vardhamana Mahavir. To answer this, we need to evaluate each given option based on historical and religious facts related to Vardhamana Mahavir, the central figure of Jainism.

Vardhamana Mahavir: Analyzing Key Statements

• Statement 1: He is considered to be 24th and last Tirthankara.

  This statement is true. Vardhamana Mahavir is indeed revered as the twenty-fourth and last Tirthankara (ford-maker) of Jainism. Tirthankaras are supreme human beings who have achieved omniscience and guide others across the ocean of worldly existence.

• Statement 2: His mother was sister of Licchavi's king Chetaka.

  This statement is also true. Vardhamana Mahavir's mother was Princess Trishala, who was the sister of King Chetaka of Vaishali. King Chetaka was a prominent ruler of the powerful Licchavi clan. This royal connection places Mahavir in an important social context of his time.

• Statement 3: He did not marry in his lifetime.

  This statement is not true. According to traditional Jain texts, Vardhamana Mahavir was married to Princess Yashoda and had a daughter named Priyadarshana (also known as Anojja). He lived a householder's life before renouncing the world at the age of 30 to pursue spiritual enlightenment and asceticism. Therefore, the assertion that he did not marry is incorrect.

• Statement 4: He left his body in 527 BCE at Pavapuri near Patna.

  This statement is generally considered true. Vardhamana Mahavir attained moksha (liberation or nirvana) at Pavapuri, located in the present-day Nalanda district of Bihar, which is near Patna. The year 527 BCE is widely accepted as the year of his nirvana by the Digambara tradition of Jainism and is a commonly cited date in historical and competitive exam contexts, although other traditions may cite 468 BCE.

Mahavir's Personal Life: The Marital Aspect

Upon reviewing all the statements, the one that stands out as incorrect is "He did not marry in his lifetime." Historical records and Jain traditions clearly state that Vardhamana Mahavir was married and had a child before embarking on his spiritual journey of renunciation. His marriage and subsequent renunciation are significant events in his biography, marking his transition from a worldly prince to an ascetic seeking ultimate truth.

Therefore, the statement that is not true in relation to Vardhamana Mahavir is Option 3.
