In Buddhism, when we hear about generating immeasurable love and compassion towards all beings, it literally means all beings without exception. It does not mean just my family, or my friends, or my people from my country, or even just human beings from my world.
It means expanding our love and compassion so that it becomes immeasurable - so that it embraces each and every sentient being throughout all of the planes of cyclic existence, no matter where they are, no matter what form that they have.
Of course, until we achieve the omniscient state of a Buddha and help countless beings simultaneously, we must accept our present limitations. Nevertheless, without losing our immeasurable love and compassion towards all beings throughout cyclic existence, we carry on living our day to day life, and simply allow these immeasurable qualities to embrace each and every being that we come across, and we try our best to benefit them, no matter who they are, or what they do. If we can't benefit them, at the very least do not harm them.
This sacred substance [the nature of everything] we have to, and should, respect, appreciate, uphold and cherish it as it is. I will give a simple example, when you feel shaky, kind of not certain
and become confused, then face a mountain and look at the mountain. Mountains do not move. And when you feel so small and so incapable..., so inferior, then look at the sky. Your mind is as limitless
as sky. You are limitless. You have no limitation. You are not inferior or incapable, that has no space. Space is limitless. Mind is like space, in fact mind is space. That is why some of you could
be born here and have come from billions of light years away, because for mind, it covers everything, it is all-pervading. Therefore, you can die billions of light years away and be born here in a
split second. It does not take millions of light years to get here.
Tai Situ Rinpoche
Look outward at the appearing objects,
And like the water in a mirage,...
They are more delusive than delusion.
Unreal like dreams and illusions,
They resemble reflected moon and rainbows.
Look inward at your own mind!
It seems quite exciting, when not examined.
But when examined, there is nothing to it.
Appearing without being, it is nothing but empty.
It cannot be identified saying, "that's it!"
But is evanescent and elusive like mist.
Look at whatever may appear
In any of the ten directions.
No matter how it may appear,
The thing in itself, its very nature,
Is the sky-like nature of mind,
Beyond the projection and dissolution of thought and
Nyoshul Khen Rinpoche
