What are the consequences of doubting a Guru's words, and what is the reward for following them without question?

As highlighted in Chapter 23, doubting the words of a saint leads to failure and spiritual barrenness. If one has doubts, their resolutions will be unsuccessful, and their speech will become hollow and fruitless, preventing them from achieving even a bit of spirituality. Conversely, the reward for following the Guru's command is immense. One who considers the Guru's words venerable succeeds in both worldly and spiritual matters. For such a devotee, the Guru's command is the ultimate authority, providing an extraordinary surge of energy. As illustrated by Kaka Dixit, for whom breaking the command was the only sin, there is no merit greater than following the Guru's order.
