Which two conditions did Kaka Mahajani's friend insist on before he would travel to Shirdi?

According to the account in Chapter 35, Kaka Mahajani's friend, who was described as being averse to idol worship, agreed to go to Shirdi only after setting two specific conditions. He firmly stated to his friend, 'We will never bow our heads, nor provide any Dakshina.' He made Kaka Mahajani agree to these terms before they set out from Mumbai on a Saturday night. This resolve stemmed from his skeptical nature and his devotion to a formless concept of the divine, making his subsequent actions at Shirdi all the more significant.
