พระอาจารย์อธิบายว่าความกังวลเป็นดวงอกุศลที่ตั้งขึ้นสลับกับดวงสมาธิ เมื่ออกุศลตั้งขึ้นก็เหนี่ยวนำบาปเข้ามา มีผลต่อวิญญาณธาตุและธาตุอื่นภายในดวงธรรมให้แปรปรวน จึงรู้สึกร้อนวูบวาบ แนะให้แก้ด้วยการรู้ทันว่าอกุศลเข้าสิง แล้วนึกถึงพระหรือทำใจให้ผ่อนคลาย โดยลองหลายวิธีตามสถานการณ์Pra Ajarn explains that worry is a sphere of the unwholesome, arising alternately with the sphere of concentration; when the unwholesome arises it draws in demerit, affecting the consciousness-element and other elements within the sphere of Dhamma, causing them to fluctuate and produce heat. He advises catching it — recognizing the unwholesome has taken hold — then recalling the Buddha or relaxing, trying several methods as the situation requires.
Someone asked: when anxious during meditation, why do they feel heat at the back, unable to sit — though it's lessened now?
Worry Is a Sphere of the Unwholesome, Alternating With the Sphere of Concentration
The sphere of worry is dark, a sphere of ; when it arises it draws in demerit. So when we worry while sitting, there's a contest: the sphere of worry arises, tries to slip in a sphere of concentration, then the sphere of worry arises again — alternating back and forth, but so fast it seems both appear at once.
The Unwholesome Affects the Consciousness-Element, Making the Elements Fluctuate
When the sphere of worry arises it draws in demerit. Everything unwholesome arises in one place only — the mind — in the (viññāṇa-dhātu), which affects things within . Within the sphere of are the elements of earth, water, wind, fire, and space, and at the center of the space-element is the consciousness-element. When the unwholesome arises, it makes the consciousness-element, space-element, and other elements fluctuate, so we feel flushes of heat here and there. If severe, the heart trembles, the body shakes; more severe still, one may faint. All of it stems from the consciousness-element — the mind possessed by the unwholesome, drawing in demerit.
Remedy by Catching It, Then Trying Several Methods as the Situation Requires
The remedy is to recognize that the unwholesome has taken hold and drawn in demerit, and remind oneself of this. We must free ourselves from the situation — don't dwell on it. Recall the grandmaster, Luang Phor, or the Buddha; or relax the mind and be at ease; or recite '' and recall the feeling of ease. Try several methods as the situation requires — one method works in one situation but not in another. So we must learn to use several, practicing various methods to have them ready to use to good effect.
