To counteract the common fear that the release of nibbana is a type of starvation, Khp 6 depicts it as a form of consumption in which one’s food is totally free — freely available, free from debt, and free from suffering.
"Perhaps to counteract the common fear that the release of nibbana is a type of starvation, Khp 6 depicts it as a form of consumption in which one’s food is totally free — freely available, free from debt, and free from suffering: § 50. Those who, devoted, firm-minded, apply themselves to Gotama’s message, on attaining their goal, plunge into the deathless, freely eating the liberation they’ve gained." — Khp 6 ~ Thanissaro Bhikkhu "The Shape of Suffering: A Study of Dependent Co-arising"
