What are the provisions for social justice in Indian Constitution?

I. Introduction: In Indian society deepand persistent divisions exist between those who enjoy greater wealth and property, and the power which goes with such ownership, and those who are excluded and deprived. In short we can say that social justice is lacking in Indian society.
II Justice Demands: Justice does not require absolute equality and sameness in the way which people live. But a society would be considered unjust if the differences between rich and poor are so great that they seem to be living in different worlds altogether and if they relatively deprived have no chance at all to improve their condition, however, they may work. In other words, a just society should provide people with the basic minimum conditions to enable them to live healthy and secure lives and develop their talents as well as equal opportunities to pursue their chosen goals in the society.
III. Provisions made to end social injustice in India: 1. The Constitution of India has declared the wrong practice of untouchability and caste discrimination of any kind is illegal.
2. The state is supposed to provide equal opportunities for all citizens of India in matter of education or employment.
3. No one can be prevented from using public facilities like wells, water-tanks, or denied entry into temples, hotels, cinema halls, any restaurants on the gound of caste or religion.
4. The Preamble to the constitution of India, Directive Principles of State Policy, Fundamental Rights and some specific sections in the Constitution of India are a proof of the commitment of the state to its people.
5.India is a welfare state committed to the welfare and development of its people in generaland to the development of the weaker sections in particular.
