The Constitution of India provides for a democratic form of governance with a federal structure. The major approaches outlined in the Constitution for governance are as follows:

• Parliamentary democracy - The Constitution provides for a parliamentary democracy with a bicameral legislature.
• Federalism - The Constitution establishes a federal structure of government where powers are shared between the central and state governments.
• Judicial Review - The Constitution establishes an independent judiciary and provides for judicial review of laws and actions of the government.
• Socialism - The Constitution pursues socialist ideals through provisions for economic and social justice for all citizens.
• Secularism - The Constitution provides for a secular state where all religions are treated equally.

These approaches have been implemented to varying degrees since the inception of the Constitution. While parliamentary democracy and federalism have been well-established in India, there have been challenges in implementing socialism and secularism. The judiciary has played a critical role in upholding the Constitution and ensuring the principles of governance outlined in it are adhered to.
