What is a sincere and earnest desire to know one's true nature? It indicates the one and only strong desire to know one's true nature. Nothing else matters. This desire to know one's true nature becomes a burning desire to the exclusion of all other desires. It is like the thirst for water for a person stranded in the desert. It is like the desire for air in a person who is drowning in water.
It is not a desire to know, so that one can be called a sage. It is not a desire to know, so that one can tell others how great it is to know your true nature. It is not a desire to know, so that there can be something to gain from it. It is not a desire to know, because one cannot face the world as it is. It is not a desire to know, so that one can escape from this world of suffering. It is not a desire to become something other than what you already are. It is not a desire to know, so that there is more knowledge.
It is just the desire to know for the sake of knowing - even if it means the end of everything that was already known and believed in. When this Knowledge dawns upon one, even this knowledge is discarded, and then all that is left is pure Being, which always IS. Just BE.
