Pursuing doctoral degree is a prestigious achievement to a doctoral student and it encompasses contribution of new knowledge to the discipline. Research conducted at this level is the most sustained and the most demanding for both doctoral student and doctoral supervisor. The supervisory practices adopted by the doctoral supervisor and the relationship between the student and supervisor plays a pivotal role in enhancing the quality of the research work done at doctoral level. A common fact about doctoral supervision is that it is seen as a privatized space or a "black box". With the growing volume of doctoral education all over the world, it is essential to break this black box and turn on lights in this private space. The present paper unveils about doctoral supervision, challenges and ways to address them. It also discusses about the areas which needs to be explored further in this direction.
