The understanding of Insight Meditation for student of Abhidhamma is not quite the same. Here is a summary from a Vipasana Bhavana Study Manual from Boonkanjanaram Meditation Center at a temple near Pattaya, Thailand.
is Kusala and it's in Vatta-Dukkha (Samsara). It existed before the Lord Buddha.
The feeling when Jhana is reached is one of being happy paermanently, and with self, atta (Moha still exists).
1) The true nature is Samadhi to create peaceful mind.
2) The object of meditation is Pannatti (conventional reality), such as kasina (meditation disc).
3) The characteristic of Samattha is no restlessness.
4) The duty of Samattha is to suppress the 5 hindrances (Nivarana): sensuality, ill-will, restlessness, sloth and doubt.
5) The result of Samattha is one-pointedness (ekaggata).
6) The effect of Samattha is a mind that desires no kammaguna (sensuous pleasures), and is content and happy in Samadhi.
7) The benefit of Samattha is that in this life, Samapatti (the eight stages of Jhana) can be entered. The mind is without Abhijjha and Domanassa and is very peaceful. In the next life, the Brahma world (Brahmaloka) can be attained.
8) In Samattha, only one object and two senses are used at any one time, such as the eye and the mind (in this case of a kasina or visual object) or touch and the mind, in the case of Anapanasati (breath).
9) According to the Scriptures, a yogi who decides to practice Samattha, should determine which of these Carita (characteristics) is predominant in him:
1) Raga Carita (lustful nature)
2) Dohsa Carita (hating nature)
3) Moha Carita (deluded nature)
4) Satta Carita (faithful nature)
5) Buddhi Carita (intelligent nature)
6) Vitakka Carita (speculative nature)
Then the Visudhimagga should be consulted for the type of Samattha meditation for the Yogi's particular Carita. For example, for a lustful nature, Asubha or meditation on corpses is recommended.
is Kusala but it is out of Samsara, and was discovered by the Lord Buddha.
The feeling when Vipassana yana is realized is that of impermanence, suffering and no-self (Annatta).
1) The true nature is Panna (wisdom).
2) The object of meditation is Paramatta (ultimate reality or rupa and nama) in the 4 foundations of Satipatthana, which leads to Vipassana wisdom.
3) The characteristic of Vipassana is wisdom, which reveals the true state of nature.
4) The duty of Vipassana is to destroy ignorance (avijja = ignorance of the 4 Noble Truths).
5) The result of Vipassana is to have the right view, (or the true state of the natures of nama and rupa).
6) The effect of Vipassana is Samadhi that has Satipatthana as an object (kanika samadhi) so Vipassana wisdom can occur.
7) The benefit of Vipassana is cessation of one's accumulations of defilements (asavakkhayanana).
With no defilements, no rebirth will occur (vivatta), which is Nibbana. Because of Nibbana, there is no rebirth and this is real happiness.
8) In Vipassana, 6 senses are used, and no special objects are needed. Simply observe rupa and nama, which are anicca, dukkha, annatta (True State of Nature). Even the hindrances (Nivarana) can be used as in Dhammanupassana (contemplation of mind objects).
9) The Lord Buddha said that one who would practice Vipassana should determine which of these Caritas resemble him. A station of Satipatthana is recommended for each of these 4 types (e.g. 1a, 1b). (For example, if the Carita is Tanha with strong wisdom (1a), the recommended station is Vedana.
1) Tanha Carita (craving nature)
a) strong wisdom
b) weak wisdom
2) Ditthi Carita (opinionated)
a) strong wisdom
b) weak wisdom
In these times, however, it has been determined that everyone has Tanha with weak wisdom, and so in this practice, Kaya meditation (major and minor positions) is used to with. According to the Lord Buddha, the Arahatta path in these time will only be attained through Kaya meditation ((major and minor positions).
