Describe the initial mindset of Kaka Mahajani's friend before visiting Shirdi and the specific conditions he set for the trip.

According to Chapter 35, Kaka Mahajani had a friend who was initially quite skeptical. He was described as being averse to idol worship and a devotee of the formless, agreeing to visit Shirdi purely out of a sense of 'clinical curiosity.' Before embarking on the journey with Kaka, he established two firm conditions. He stated to his friend, 'We will go to Shirdi and only take the Darshan of the saint; We will never bow our heads, nor provide any Dakshina.' Only after Kaka agreed to these terms did the friend, who was otherwise prone to doubts, set out from Mumbai with a healthy mind.
