“A close examination of the instructions in the Satipaṭṭhāna Sutta reveals that the meditator is never instructed to interfere actively with what happens in the mind. If a mental hindrance arises, for example, the task of satipaṭṭhāna contemplation is to know that the hindrance is present, to know what has led to its arising, and to know what will lead to its disappearance. A more active intervention is no longer the domain of satipaṭṭhāna, but belongs rather to the province of right effort (sammā vāyāma).The need to distinguish clearly between a first stage of observation and a second stage of taking action is, according to the Buddha, an essential feature of his way of teaching. The simple reason for this approach is that only the preliminary step of calmly assessing a situation without immediately reacting enables one to undertake the appropriate action.”

“The Pāli term for "feeling" is vedanā, derived from the verb vedeti, which means both "to feel" and "to know". In its usage in the discourses, vedanā comprises both bodily and mental feelings. Vedanā does not include "emotion" in its range of meaning. Although emotions arise depending on the initial input provided by feeling, they are more complex mental phenomena than bare feeling itself and are therefore rather the domain of the next [third] satipaṭṭhāna, contemplation of states of mind.”

“On considering these instances it is indubitably clear that sati has a crucial role to fulfill in the realm of samatha. This might be why the Cūḷavedalla Sutta speaks of satipaṭṭhāna as the "cause" of concentration (samādhinimitta)....On the other hand, however, to consider satipaṭṭhāna purely as a concentration exercise goes too far and misses the important difference between what can become a basis for the development of concentration and what belongs to the realm of calmness meditation proper. In fact, the characteristic functions of sati and concentration (samādhi) are quite distinct. While concentration corresponds to an enhancement of the selective function of the mind, by way of restricting the breadth of attention, sati on its own represents an enhancement of the recollective function, by way of expanding the breadth of attention. These two modes of mental functioning correspond to two different cortical control mechanisms in the brain. This difference, however, does not imply that the two are incompatible, since during absorption attainment both are present. But during absorption sati becomes mainly presence of the mind, when it to some extent loses its natural breadth owing to the strong focusing power of concentration.”

“Whether our action is wholesome or unwholesome depends on whether that action or deed arises from a disciplined or undisciplined state of mind. It is felt that a disciplined mind leads to happiness and an undisciplined mind leads to suffering, and in fact it is said that bringing about discipline within one's mind is the essence of the Buddha's teaching.”

“Observe & accept what ever arises & know that everything is as it needs to be.”

“A purely mental life may be destructive if it leads us to substitute thought for life and ideas for actions. The activity proper to man is purely mental because man is not just a disembodied mind. Our destiny is to live out what we think, because unless we live what we know, we do not even know it. It is only by making our knowledge part of ourselves, through action, that we enter into the reality that is signified by our concepts.”
