Lama Ole’s answer:
As a good student of mine, you should do what you always do: think of everything pleasant as a blessing that you want to pass on to all beings, and everything unpleasant as a purification and a teaching on how to help others. Whatever happens, we rest in it, enjoy it, and don’t create strange ideas about it.
Then if it appears naturally, we can expand it. You might know the energy centers in the body: four fingers below the navel, in the navel, in the heart, in the throat, and in the head. If we perceive energy in one or another location, then we pull the energy towards the heart and from there radiate it out to all beings. If we bring the experience to the center of our chest at heart level, then it works in the most well-rounded way.
If we have a lot of thoughts in our heads and can’t come to rest, then we pull everything down to the heart and radiate it out from there. If there is a lot of energy in the lower chakras, then we also take this energy up to the heart and radiate it out from there. Wherever there is surplus, pull that to your heart and expand it. If we can give up the feeling of separation between ourselves and our partners, then some of the general energies in the lateral channels of our body will enter the central channel. This then results in different states and experiences of openness within the body.
The same happens if one learns to hold this state in meditation, filling up the entire upper body from the heart and the lower body from the navel. In meditation, most of the time it happens through openness and dedication, through courage and joy. In love, it happens through the female and the male complementing each other. But we also shouldn’t create too many concepts about it since it isn’t easy.
