I have recently posted an answer to a question very similar to yours. In there i write about The Five Hindrances and give references to a book and an audio dhamma talk on the topic. In the book and audio talk a thourough description of the hindrances and their antidotes are given.
The hindrances are what blocks one from developing in meditation. When the mind is obscurred by concepts, desires, doubts etc. and therefore not being able to "see clearly" there will be wavering in the mind. When there is wavering in the mind the true nature of phenomena cannot be seen, i.e. the 3 signs of existence.
There are different ways to deal with the hindrances. As Ven. Bhikkhu Bodhi talks about in the audio dhamma talk one can note the hindrance a couple of times and return to the primary object of meditation e.g. the rising and falling of the abdomen. The hindrance might come back multiple times and with greater intensity. One can then leave the abdomen and instead take the hindrance as a primary meditation object. If that does not work too then one can begin to administer antidotes to the hindrance. See the quote in next section.
- SENSUAL DESIRE
A. Nourishment of Sensual Desire
There are beautiful objects; frequently giving unwise attention to them — this is the nourishment for the arising of sensual desire that has not arisen, and the nourishment for the increase and strengthening of sensual desire that has already arisen.
— SN 46:51
B. Denourishing of Sensual Desire
There are impure objects (used for meditation); frequently giving wise attention to them — this is the denourishing of the arising of sensual desire that has not yet arisen, and the denourishing of the increase and strengthening of sensual desire that has already arisen.
— SN 46:51
Six things are conducive to the abandonment of sensual desire:
Learning how to meditate on impure objects;
Devoting oneself to the meditation on the impure;
Guarding the sense doors;
Moderation in eating;
— Commentary to the Satipatthana Sutta
- Learning how to meditate about impure objects
& 2. Devoting oneself to the meditation on the impure
(a) Impure objects
In him who is devoted to the meditation about impure objects, repulsion towards beautiful objects is firmly established. This is the result.
— AN 5:36
"Impure object" refers, in particular, to the cemetery meditations as given in the Satipatthana Sutta and explained in the Visuddhimagga; but it refers also to the repulsive aspects of sense objects in general.
(b) The loathsomeness of the body
Herein, monks, a monk reflects on just this body, confined within the skin and full of manifold impurities from the soles upward and from the top of the hair down: "There is in this body: hair of the head, hair of the body, nails, teeth, skin, flesh, sinews, bones, marrow, kidneys, heart, liver, pleura, spleen, lungs, intestines, bowels, stomach, excrement, bile, phlegm, pus, blood, sweat, fat, tears, lymph, saliva, mucus, fluid of the joints, urine (and the brain in the skull)."
— MN 10
By bones and sinews knit,
With flesh and tissue smeared,
And hidden by the skin, the body
Does not appear as it really is...
The fool thinks it beautiful,
His ignorance misguiding him...
— Sutta Nipata, v.194,199
(c) Various contemplations
Sense objects give little enjoyment, but much pain and much despair; the danger in them prevails.
— MN 14
The unpleasant overwhelms a thoughtless man in the guise of the pleasant, the disagreeable overwhelms him in the guise of the agreeable, the painful in the guise of pleasure.
— Udana, 2:8
- Guarding the sense doors
How does one guard the sense doors? Herein, a monk, having seen a form, does not seize upon its (delusive) appearance as a whole, nor on its details. If his sense of sight were uncontrolled, covetousness, grief and other evil, unwholesome states would flow into him. Therefore he practices for the sake of its control, he watches over the sense of sight, he enters upon its control. Having heard a sound... smelt an odor... tasted a taste... felt a touch... cognized a mental object, he does not seize upon its (delusive) appearance as a whole... he enters upon its control.
— SN 35:120
There are forms perceptible by the eye, which are desirable, lovely, pleasing, agreeable, associated with desire, arousing lust. If the monk does not delight in them, is not attached to them, does not welcome them, then in him thus not delighting in them, not being attached to them and not welcoming them, delight (in these forms) ceases; if delight is absent, there is no bondage. There are sounds perceptible by the ear... odors perceptible by the mind... if delight is absent, there is no bondage.
— SN 35:63
- Moderation in eating
How is he moderate in eating? Herein a monk takes his food after wise consideration: not for the purpose of enjoyment, of pride, of beautifying the body or adorning it (with muscles); but only for the sake of maintaining and sustaining this body, to avoid harm and to support the holy life, thinking: "Thus I shall destroy the old painful feeling and shall not let a new one rise. Long life will be mine, blamelessness and well-being."
— MN 2; MN 39
- Noble friendship
Reference is here, in particular, to such friends who have experience and can be a model and help in overcoming sensual desire, especially in meditating on impurity. But it applies also to noble friendship in general. The same twofold explanation holds true also for the other hindrances, with due alterations.
The entire holy life, Ananda, is noble friendship, noble companionship, noble association. Of a monk, Ananda, who has a noble friend, a noble companion, a noble associate, it is to be expected that he will cultivate and practice the Noble Eightfold Path.
— SN 45:2
- Suitable conversation
Reference is here in particular to conversation about the overcoming of sensual desire, especially about meditating on impurity. But it applies also to every conversation which is suitable to advance one's progress on the path. With due alterations this explanation holds true also for the other hindrances.
If the mind of a monk is bent on speaking, he (should remember this): "Talk which is low, coarse, worldly, not noble, not salutary, not leading to detachment, not to freedom from passion, not to cessation, not to tranquillity, not to higher knowledge, not to enlightenment, not to Nibbana, namely, talk about kings, robbers and ministers, talk about armies, dangers and war, about food and drink, clothes, couches, garlands, perfumes, relatives, cars, villages, towns, cities, and provinces, about women and wine, gossip of the street and of the well, talk about the ancestors, about various trifles, tales about the origin of the world and the ocean, talk about what happened and what did not happen — such and similar talk I shall not entertain." Thus he is clearly conscious about it.
But talk about austere life, talk suitable for the unfolding of the mind, talk which is conducive to complete detachment, to freedom from passion, to cessation, tranquillity, higher knowledge, enlightenment and to Nibbana, namely, talk about a life of frugality, about contentedness, solitude, aloofness from society, about rousing one's energy, talk about virtue, concentration, wisdom, deliverance, about the vision and knowledge of deliverance — such talk I shall entertain." Thus he is clearly conscious about it.
— MN 122
These things, too, are helpful in conquering sensual desire:
One-pointedness of mind, of the factors of absorption (jhananga);
Mindfulness, of the spiritual faculties (indriya);
Mindfulness, of the factors of enlightenment (bojjhanga).
