Discuss the importance of the Article 16 of the Constitution in reference of fulfillment of the Right to Equality of opportunity?

Our Constitution mentions Equality of Status and Equality of Opportunity.
 The government is supposed to implement special schemes and measures to
improve the conditions of certain sections of society.
 There is provision for reservations in jobs and admissions for children, women and
socially and educationally backward classes despite we follow the principle of
equality.
 Article 16 (4): explicitly clarifies that a policy of reservation will not be seen as a
violation of Right to Equality. If we try to find out the spirit of Constitution this is
required for the fulfillment of the Right to Equality of opportunity.
 Article 16 (4): nothing in this article shall prevent the state from making any
provision for the reservation of appointments or posts in favour of any backward
class of citizens which, in the opinion of State, is not adequately represented in the
services under the State.
