Samyama
The combined practice of dharana (concentration) dhyana (meditation) and samadhi (auto-realization).
Patañali Sutras 3.1.-3.6.

Ānāpānasati

You will develop some mastery over your wild mind by training it to remain fixed on a single object, the breath.

One tries to keep one's attention on the respiration for as long as possible.

This is not a breathing exercise; one does not regulate the breath.

Instead, one observes natural respiration as it is, as it comes in, as it goes out.

In this way one further calms the mind so that it is no longer overpowered by intense negativities. At the same time, one is concentrating the mind, making it sharp and penetrating, capable of the work of insight.

Vipassanā

Vipassana (Pali) means to see things as they really are.
The practice of this ancient technique helps you to realize that nothing is permanent - there is constant changing going on (anicca).
The acceptance of this and the continuously analytic observation of yourself leads to experiential knowledge of the truth (bhavana mayapanna) to experiential wisdom.

The understanding of this leads to real peace and real happiness.

May all beings be happy, peaceful and liberated!
