การดูกายสิทธิ์ในดวงแก้วต้องอาศัยความสว่างและความบริสุทธิ์จากการเข้าถึง 18 กาย มิฉะนั้นอาจเห็นเป็นเพียงนิมิตที่ถูกอกุศลบิดเบือน กายสิทธิ์ไม่หายไปไหนแต่ทำงานได้มากน้อยตามกำลังบุญของเรา และต้องระบุความต้องการให้ชัดเจนเหมือนสั่งงานผู้ช่วยSeeing the guardian spirit inside a crystal ball requires brightness and purity gained through reaching the 18 bodies — otherwise what appears may just be a vision distorted by unwholesome influence. The guardian never disappears, but its ability to help scales with our own merit, and we must clearly state what we need, much like instructing an assistant.
Someone asked: those who receive a crystal ball during their ordination — how should they care for it? And for those who haven't yet learned the technique, how can they perceive the guardian spirit within?
The teacher explained the method: take the cool crystal ball into the finest, most subtle point at , still the mind there, and let the crystal expand — the being within it will then become visible. Whatever you wish to know, you may ask that being directly. But to do this requires first cultivating inner brightness; otherwise, obscuring elements will block the view entirely.
The most reliable path is to reach the -sphere and the eighteen bodies through the dhamma-eye. Reaching the dhamma-sphere already represents a degree of sufficient to see, even without the full dhamma-eye — though at that stage, perception can still be distorted by unwholesome influence and defilement. Without enough purity, what one perceives may be nothing more than an unreliable vision, disconnected from the truth. What matters most is perceiving things exactly as they are, not the voice of an unwholesome, dark influence fabricating things within the mind.
The teacher went on to explain that everything in this world is exchanged through merit — nothing comes for free. Whether human, celestial, or Brahma being, all sustain their existence through merit. The guardian in the crystal is bound to the body — it travels wherever we go and helps whenever we ask. But requests demanding greater resources require correspondingly greater accumulated merit. What the guardian alone cannot manage, a higher "merit-emperor" steps in to resolve; and beyond that lies the level of a Buddha-emperor. Those who have devoted themselves deeply to building merit will have correspondingly greater guardians looking after them.
Someone asked whether forgetting to dedicate merit to the guardian would cause it to vanish. The teacher answered no — it remains and continues fulfilling its duty to help. But when we dedicate merit to it regularly, the guardian is gladdened and grows more motivated to assist us.
Another question was whether the guardian can sense our wishes without our stating them. The teacher said no — only guardians of a much higher order, on the level of celestial royalty, can read intent unspoken. For an ordinary person, one must clearly state what is needed, much as one would instruct an assistant. This need to ask clearly is itself a form of training in and effort — much like parents who do everything for a child end up raising someone who can do nothing for themselves. Cultivating diligence and endurance is necessary.
Finally, the teacher recommended practicing the preceptor's ten daily exercises — especially setting an alarm every hour, pausing whatever one is doing, and taking one minute to connect with the Triple Gem and Nibbāna, allowing that connection to refine and purify one's inner elements. Practiced consistently, this shapes daily life continuously within system.
