What are the Effects of the 4 Feet of Spiritual Force?
The Blessed Buddha once said: When a Bhikkhu develops the Feet of Force that is enriched with concentrated desire, concentrated energy, concentrated thought & concentrated investigation, all constructed by effort, by thinking: In this way will my desire, energy, thinking and investigating neither be too slack nor too tense, it will neither be constricted internally nor scattered externally, then he dwells experiencing both what is in front & what is behind, so above, so also below, so by day, so also at night! Therefore, with a mind that is all open & unrestricted, he develops the dazzling bright mind, which is pervaded by luminosity... When the 4 feet of suprahuman force have been developed, refined and cultivated in exactly this way, the Bhikkhu possesses the various kinds of suprahuman force: With the divine eye, which is purified & surpasses the human, he sees beings passing away and being reborn, as inferior or superior, beautiful or ugly, fortunate & unfortunate, and he understands how beings travel on in accordance with their actions (=kamma) thus: The beings who misbehaved bodily, verbally and mentally, who reviled the Noble Ones, held wrong view, and did actions based on wrong view, with the break-up of their body, right after death, they have been reborn in a state of misery, in a painful destination, in the lower worlds, even in hell! But these other beings who engaged in good behaviour bodily, verbally & mentally, who did not revile the Noble Ones, who held right view, & undertook action based on right view, with the break-up of their body, after death, have been reborn in a good & happy destination, even a divine world! Thus with the divine eye, which is purified and surpasses the human, he sees beings passing away and being reborn, inferior and superior, beautiful and ugly, fortunate and unfortunate, and he understands how beings is reborn on in accordance with their kamma (behaviour).
