What is the process of amending the constitution

Amending the Constitution of India is laid down in Part XX (Article 368) of the Indian Constitution. As the Constitution of India is flexible as well as rigid, it is evident that not all parts of it can be amended. For example the Basic structure laid down by the Supreme Court in the case of Kesavananda Bharati v. State of Kerela, is beyond amendment.

The amendment can be initiated only via the introduction of a bill in either of the house of the Parliament. The bill must then be passed in each House by a majority of the total majority of that house and by a majority of not less than two-thirds of the members present and voting. It is then ratified and assented by the President.
