The Preamble to the Constitution of India outlines the guiding principles and objectives of the Indian Constitution. It serves as an introductory statement that sets the tone for the entire document. While the Preamble embodies several objectives, one of the objectives that is not explicitly mentioned in the Preamble is "Economic liberty".

1. Preamble to the Constitution of India:
The Preamble begins with the phrase "We, the people of India" and highlights the aspirations and goals of the Indian citizens. It states that the Constitution is adopted to secure certain objectives, which are:

a) Justice: The first objective mentioned in the Preamble is to secure justice - social, economic, and political. This emphasizes the importance of a fair and equitable society where every individual has equal opportunities and access to justice.

b) Liberty: The Preamble also aims to secure liberty to all citizens. It encompasses various aspects of liberty, such as freedom of thought, expression, belief, faith, and worship. It ensures that individuals have the right to express themselves freely without any undue restrictions.

c) Equality: The Preamble seeks to promote equality in all spheres of life. It guarantees equality of status and opportunity to all citizens, irrespective of their caste, religion, gender, or place of birth. The principle of equality ensures that there is no discrimination and everyone is treated equally under the law.

d) Fraternity: The Preamble emphasizes the need for fostering a sense of brotherhood and unity among the people of India. It promotes the spirit of fraternity and ensures that there is harmony and cooperation among citizens, transcending barriers of religion, language, or region.

2. Economic Liberty not mentioned:
While the Preamble mentions liberty in various forms, including thought, expression, and belief, it does not explicitly mention "economic liberty". Economic liberty refers to the freedom of individuals to engage in economic activities without unnecessary government interference. It includes aspects such as the right to own private property, conduct business, and pursue economic opportunities.

The absence of economic liberty in the Preamble does not mean that it is disregarded or neglected by the Constitution. The Constitution of India contains several provisions that safeguard economic rights. For example, Article 19 guarantees the freedom to practice any profession, occupation, or trade. Additionally, various fundamental rights and directive principles of state policy address economic issues and strive for economic justice.

In conclusion, the Preamble to the Constitution of India does not explicitly mention "economic liberty" as one of its objectives. However, this does not undermine the significance of economic rights, as they are protected and promoted through other provisions of the Constitution.
