Why did Baba test Kaka Dixit, even though he knew Kaka was like 'pure gold'?

Although Baba knew Kaka Dixit's mind was pure, the test was conducted for the benefit of others. Chapter 23 explains that people often do not believe words alone and need proof, just as gold is tested in fire to satisfy onlookers of its purity. Divine glory is not achieved without enduring trials, much like a diamond must endure the blows of a hammer to reveal its brilliance. By ordering Kaka to prepare to kill the goat, Baba provided a public demonstration of Kaka's unwavering faith and obedience, solidifying his spiritual stature in the eyes of others and proving the power of a Guru's command.
