How does Sai Baba connect the concepts of faith and patience to spiritual attainment?

Sai Baba teaches that full faith and patience are paramount for spiritual progress, personifying them as the divine figures of Parvati and Shiva. According to the teachings in Chapter 37, it is only with their 'hands of grace' on one's head that the Lord of the Universe dwelling within the heart can be seen. The great Guru Sai Nath reinforces this by stating that his words are of infallible power and that with 'a little patience of faith,' a devotee is assured to attain great glory. This illustrates that these qualities are not merely virtues but the essential foundation for receiving the grace necessary for spiritual realization.
