How does Chapter 10 contrast the path of devotion to a Guru with other spiritual or intellectual pursuits?

Chapter 10 champions the path of devotion to a Sadguru as the most effective means to liberation, contrasting it with more complicated methods. The text asserts that where the service of the Sadguru is pure, the worldly existence (Samsara) is completely destroyed. It explicitly states that with this path, "there is no need for the struggle of logic, Mimamsa, or other intellectual acrobatics." The chapter emphasizes that simply remembering the Guru with a loving heart is the best Sadhana, costing nothing yet yielding great fruit. This path of faith is presented as a straightforward way to overcome the three types of miseries and attain blissful liberation, which the Guru places in the devotee's hand effortlessly.
