Can my landlord evict me with just a week's notice?

I'm living in a rented apartment in Mumbai for the past 2 years, and my lease is valid for another 6 months. Suddenly, my landlord is asking me to vacate the flat within a week due to his personal reasons. I've always paid the rent on time and haven't breached any clauses in the agreement. I'm worried about finding a new place at such short notice. Is it legal for him to ask me to leave like this, and what are my rights as a tenant in this situation?
