Any of you interested to learn metta meditation let me know. I can give you the details of the series of metta meditation course in PJ / Subang vicinity, conducted by Burmese monk under SJVM.

Metta (loving-kindness) is one of the 4 brahma viharas (sublime states of the brahma gods) that is
1. Metta
2. Karuna (Compassion)
3. Mudita (Sympathetic joy)
4. Upekkha (Equanimity)

One who dwells in these states are said to be dwelling in the abodes of the Brahmas (high divinity).

Well, there are many ways to do this type of meditation. I understand there are people who follow the instruction to direct the metta to the deities around them. It is mentioned there are some deities who are friendly , and some who are not so friendly.

This is especially important for monks who enter a forest to do meditation, and they direct metta to the invisible beings in the forest to ask for protection against the 'not-so-friendly' ones. If i remember correctly, there are recorded cases of monks who were disturbed by terrifying images in the forest during the Buddha's time. This was due to the unfriendly deities manifesting themselves. These monks went to the Buddha, and the Buddha taught them to direct Metta to those deities. AFter that, they did not encounter anymore disturbances there.

Of course, it's for everyone who does metta.

That one we don't know for sure unless you can see them. Even there is no Devas around you at that time, you can still derive other benefits from this meditation, good karma being one of them..
