According to the teachings, what is the connection between detachment, knowledge, and liberation, and why is this path so challenging?

The teachings in Chapter 19 outline a clear progression: liberation is impossible without knowledge, and knowledge cannot be attained without detachment. The primary challenge arises because the mind struggles to perceive the world as transient. This difficulty is due to the illusion of the universe, described as a 'false play of Maya in pure consciousness.' This illusion distracts and bewilders the spiritual traveler, making it hard to develop the necessary detachment. The text states that all worldly affairs are like the arrangements of a dream, and true awakening from the bonds of grief and delusion only comes through the 'science of the oneness of the Self,' not through any other means.
