How does the concept of a seeker's 'eligibility' influence a Guru's teachings, particularly in relation to overcoming attachments like greed?

The provided text from Chapter 17 reveals that a Guru's guidance is tailored to the seeker's spiritual readiness or "eligibility." It is mentioned that "saints first look at their eligibility; they give to them exactly according to their suitability or unsuitability." This is crucial because teaching someone who lacks the necessary purity of heart is futile. For a mind consumed by greed and worldly desires—a 'distracted mind'—the Guru's teaching is described as a "waste of effort." True spiritual science is considered "hollow" if the seeker is not yet disgusted with the desire for fruits. Therefore, a Guru assesses whether a disciple has begun to overcome attachments before imparting deeper knowledge.
