What is the stated significance of performing 'auspicious invocations' at the beginning of a task, according to Chapter 1?

According to Chapter 1 of the Sai Satcharitra, performing 'auspicious invocations,' or Mangalacharan, is a traditional etiquette followed by the wise. The significance is explicitly stated to be twofold. First, the reason for this practice is 'the removal of all obstacles,' ensuring a smooth and unimpeded process. Second, the purpose is 'the fulfillment of the desired goal.' The author follows this tradition by bowing to deities like Ganapati, who is described as holding a 'bright axe in his hand to destroy the obstacles of your devotees,' thereby seeking divine grace for the successful and obstacle-free completion of writing the sacred text.
