From: Shamar Rinpoche “Meditation in Theravada and Mahayana Traditions”
Once you connect genuinely with meditation practice, you will develop a true passion for it and your practice will begin to mature. As long as you do not understand the essence of meditation, it hasn’t been properly experienced. Only when you experience the essence does it really get interesting.
Meditation by concentration of the mind to remove the Five Hindrances is known as samatha , while the contemplation of physical body, feelings, mental functions and phenomena (dhamma) to develop Right Wisdom is called vipassana . The Vijja Dhammakaya approach includes aspects of both samatha and vipassana meditation .
