The following quote is from Sayadaw U Indaka of Chan Myay Maying in Metta: The Practice of Loving-Kindness As the Foundation for Insight Meditation Practice. As noted in a previous post, he will be teaching intensive metta retreats in Pyin Oo Lwin for those English-speaking meditators who are interested.
One day Chanmyay Sayadaw said, “I have a natural affinity for metta meditation, and I enjoy it very much. When I practise metta meditation, my mind becomes happier and more peaceful with anodisa metta (non-specific metta) than with odisa metta (specific metta). However with anodisa metta, concentration does not become very powerful and strong. I always encourage the monks and volunteers at the monastery to practise metta meditation, and I also tell the yogis who come to practise meditation at Chanmyay Yeiktha Meditation Centre to develop metta. When I tell them to practise metta meditation, I ask them to do metta at the beginning of their vipassana meditation as part of the preliminary preparations. Or else, I advise them to develop metta during vipassana meditation when the mind becomes filled with anger or when the mind is very restless. Occasionally, I also tell them to practise Buddhanussati. Sometimes, I instruct yogis who are experienced in the practice of vipassana meditation to develop metta continuously for about one to one and a half months. Some yogis who have practised in this way have had a direct personal experience of the ‘taste’ of metta.---
