Evaluate the functional characteristics and specific mandates associated with the Directive Principles of State Policy:
1. The directives function primarily as negative constitutional limitations, actively restricting the legislative scope of the state.
2. The jurisprudential equilibrium maintained between the Directive Principles and Fundamental Rights is legally recognized as a component of the 'basic structure'.
3. The framework explicitly contains a mandate instructing the state to isolate and separate the executive branch from the legislative branch.
