This is a survey article on Sasakian geometry which has emerged as one of the most powerful tools of constructing and proving existence of special Riemannian metrics, such as Einstein metrics or metrics of positive Ricci curvature on a wide range of odd-dimensional manifolds. The key geometric object in the theory is that of a contact structure (hence only odd dimensions) together with a Riemannian metric naturally adapted to the contact form.
