Why is it important to 'know ignorance first' on the path to liberation?

The instruction to 'know ignorance first,' found in Chapter 50, is a critical step towards liberation. It implies that one must first become aware of and understand the nature of Avidya, the ignorance that soils the mind and creates bondage. The text suggests that only when the 'wisdom and its exposition occur' regarding ignorance itself can its bondage be destroyed. Devotion is presented as the 'proof' and method for this process. It is by confronting and understanding ignorance that one can begin to remove it, much like one must identify and 'discard the stones' from rice before it can be cooked and consumed.
