Can I live in Spain permanently if I buy a house?

Could you please clarify for me, would it be possible for me to reside in Spain indefinitely if I purchase a property there? I'm interested in potentially settling down in Spain and want to ensure that purchasing a house would be sufficient for obtaining permanent residency. Could you elaborate on the requirements and procedures involved in this process? Would buying a house alone be sufficient, or are there additional steps I need to take? Thank you for your assistance in clarifying this matter for me.
