There is a very interesting benefit related to meditation. It is said that with loving-kindness it is easy to experience samadhi, one-pointedness. This is why I emphasise friendliness so much in the practice, because when we are practising, if you are hating things, if you are resisting things, if you are fighting things, it is not easy to have a mind that is calm. This calmness comes naturally when there is friendliness, when there is gentleness, when there is openness. So this is a very important point to remember in our practice; we are learning to use friendliness and gentleness in whatever technique we are practising.
