According to Chapter 19, how do correct knowledge, meditation, and the Guru interrelate on the path to Samadhi?

Chapter 19 presents a clear spiritual framework where correct knowledge, meditation, and the Guru are deeply interconnected. Baba clarifies that "Meditation is more important than knowledge; for that, correct knowledge is required." This correct knowledge is the understanding of the ultimate Reality (Vastu), specifically the non-dual nature of the Self. The Guru is the one who embodies and imparts this knowledge. Since the Guru, God, and the Inner Self are one, the Guru is the source of the correct knowledge needed for correct meditation. This practice, when matured, leads to Samadhi, where the meditator dissolves and the mind becomes still, like a lamp in a windless place.
