The Constituent power of Parliament to amend the Constitution

Part XX of Article 368 empowers the Parliament to amend Constitution by way of addition, variation or repeal of any provision according to the procedure laid down therein, which is different from the procedure for ordinary legislation.
Article 368 has been amended by the 24th and 42nd Amendments in 1971 and 1976 respectively. New clauses 368 (1) and 368 (3) were added by the 24th Amendment in 1971, which also added a new clause (4) in article 13 which reads, "Nothing in this article shall apply to any amendment of this Constitution made under article 368."
Amending the constitution of India is the process of making amendments to the fundamental law or supreme law of the country.
The amendment process in the constitution is set out in Part XX (Article 368) of the Indian Constitution.
This procedure preserves the sanctity of India's Constitution and holds a check on the Indian Parliament's arbitrary power.
Article 368 does not set down the legislative process to be followed at various points of the amendment.
