What is the significance of having both faith and patience on the spiritual path, according to Sai Baba?

According to the teachings in Chapter 37, full faith and patience hold immense significance, to the point where they are described as the personified forms of Parvati and Shiva. The text emphasizes that unless their hands of grace are on one's head, it is impossible to see the Lord of the Universe who resides within the heart. The great Guru Sai Nath's words, noted as having infallible power, state that with just a little patience and faith, one can attain great glory. This highlights that these qualities are not merely virtues but essential prerequisites for spiritual realization and seeing beyond the visible world.
