How does the principle of 'as you sow, so shall you reap' apply to a devotee's spiritual practice according to Sai's teachings?

The teachings in Chapter 19 firmly place the responsibility for spiritual progress on the individual's actions. The text highlights the principle "Ye yatha mam" (As they approach me...), indicating that the Lord's response is directly tied to the devotee's efforts. It is stated that "As the action, so the hearing; as the practice, so the benefit," which is presented as the core secret of the chapter. This is compared to physical exercise; one must do the work (Zor) themselves, and they cannot expect the Guru to drink the milk for them. The Lord provides well-being (Yogakshema) only for those who are constantly united with Him through their own undivided attention and practice.
