The five hindrances are sensual desire, ill will, sloth and torpor, restlessness and remorse, and doubt. They obstruct clear seeing and collectedness, but their appearance is not a moral catastrophe. In satipaṭṭhāna, the meditator knows when a hindrance is present, how it arose, how it is abandoned, and how it can be prevented from returning. This fourfold knowledge turns difficulty into curriculum.
Sensual desire promises satisfaction through an attractive object. Ill will narrows experience around resistance and harm. Sloth and torpor sink energy and clarity. Restlessness and remorse scatter the mind between agitation and replay. Doubt cannot commit to the next wholesome step. Traditional remedies include guarding the senses, contemplating unattractive aspects, loving-kindness, brightening energy, calming the body, confession and ethical repair, asking wise questions, and sustained attention to causes.
The hindrances are compared to debt, sickness, imprisonment, slavery, and a dangerous desert journey. Another set of similes compares a mind under their influence to water colored by dye, boiling, covered with algae, stirred by wind, or muddy in darkness. The problem is not that water exists; it cannot reflect clearly under those conditions.
The seven awakening factors are mindfulness, investigation of Dhammas, energy, rapture, tranquility, concentration, and equanimity. Mindfulness recognizes what is happening and keeps the teaching in view. Investigation, energy, and rapture enliven a dull mind. Tranquility, concentration, and equanimity settle an agitated mind. The Buddha explicitly teaches balance: when the mind is sluggish, calming factors are poorly timed; when excited, energizing factors are poorly timed.
Practice becomes skillful when it stops applying one medicine to every condition. A sleepy meditator may need upright posture, light, reflection, or walking. An agitated meditator may need gentler attention, bodily relaxation, and steadiness. A teacher helps distinguish a temporary state from a persistent obstacle requiring changes in conduct, schedule, or method.
Release from the hindrances is likened to paying off a debt, recovering from illness, leaving prison, gaining freedom from slavery, and crossing a desert safely. Joy arises because a real burden has been removed.
The Buddha explains that investigation, energy, and rapture are unsuitable when the mind is excited but useful when sluggish; tranquility, concentration, and equanimity are unsuitable when sluggish but useful when excited. Mindfulness, like salt, is useful everywhere.
