Can the President of India stop you from approaching the Supreme Court to secure your Fundamental Rights?

No, the President of India even can not stop me from approaching die Supreme Court to secure my Fundamental Rights because the Fundamental Rights have been enshrined in our Constitution.
This means that our Constitution provides and protects these rights arid they can not be taken away or violated by any person or government action or law, which also includes the President of India.
The Right to Constitutional Remedies is a Fundamental Right, according to which we have the right to approach the Supreme Court in case of violation of rights by any person or government or law. So, nobody can stop us from going to court to secure our Fundamental Rights.
