Practice Loving-Kindness Meditation
The practice of loving-kindness meditation (or LKM) is very easy to do, and can and should be modified based on your preferences.
The general idea behind LKM is that you’re sending well-wishes, or positive thoughts, to yourself and others.
To do this, typically it’s suggested that you start with a mantra of some sort. I’d suggest starting with this:
May they be well. May they be happy.
May they be healthy. May they be at peace.
May they be free from pain and suffering.
And the actual people you’re sending well-wishes or positive thoughts to are (in this specific order):
First: You
Second: A respected person/someone who has deeply cared for you
Third: A friend or family member
Fourth: Someone neutral
Fifth: Someone you dislike
Sixth: All beings. Expand the feelings you've generated thus far to all beings in the world.
(Taking this as the basis for the meditation, here are the instructions for practicing loving-kindness meditation:
Hold an image of the person in your mind. Make this image as clear as possible and feel your connection with the person.
Generate feelings of love. Chant/say your mantra to yourself or picture beautiful imagery.
Imagine sending those feelings of love to the person. Let those feelings swell as high as they will go.
Imagine transferring those feelings of love to the next person. From you to someone you respect/who cared for you, then to a friend/family member, then to someone neutral, then to someone you dislike, and finally to all beings.
The general advice for beginning practice is to focus on each person for 3-5 minutes and generating love for them before transferring it and moving on to the next person.)
If you do this, the meditation will take just 15-20~ minutes.
