Two factors that make the Constitution of India a living document are:

1. Amendment Procedure: The Constitution of India can be amended according to the changing needs of the society. The amendment procedure is a flexible mechanism that allows for the Constitution to be updated with the changing times. The Constitution has been amended several times since its inception, with the latest amendment being made in 2019. The amendment procedure ensures that the Constitution remains relevant and up-to-date.

2. Fundamental Rights: The Constitution of India guarantees fundamental rights to its citizens. These rights are not absolute and can be restricted in certain circumstances. The interpretation of these rights has evolved over time through the judicial process. The Supreme Court has played a significant role in expanding the scope of these rights, making them more inclusive and relevant to the changing times. For example, the right to privacy was not explicitly mentioned in the Constitution, but the Supreme Court recognized it as a fundamental right in 2017.
