no one to harm, emptiness in form

"if you can empty your boat, while crossing the river of the world, no one will oppose you and no one will seek to harm you." - Jack Kornfield.

in life, someone may seek to harm you, and many will oppose you.
the intention of the phrase, quoted above, is not to say that after reaching some state of liberation people will no longer oppose you, or seek to harm you. the reason for saying such a phrase is not to teach you something, but rather to ignite a vision from within, a realization. the author or speaker is fully aware that people will oppose and harm us, his point is not to deny this fact.

the central subject of this phrase is the ego, or self, I, me, you.
and the intended affect is to enable us to look within, to let go of unnecessary clinging to our ego, to the "I" to which we are attached. in recognizing that we have an ego, when we go further into analysis of our identity, we see our selves in relation to the world and other people. we see "who we think we are." if we are honest in our enquiry we can see that the "I" is a conglomerate of images, thoughts, wishes, impressions, craving, desire, etc... and even perhaps an emulation of an ideal self, who we want to become is included there as well. when we boil all these down we can say that generally the ego is not much more then a thought, an impression, an illusion, a memory, a wish.

what happens, when one realizes, that the self is only a thought?
well, we are given a choice, do we feed our thoughts more thoughts, or do we set out to find what and who we really are. What is beyond our thoughts. 

when we no longer hold onto thoughts, there can be no thought that can harm us. we may feel pain or become ill, but the less we associate with our thoughts, the less we will suffer in life.
how do I find myself?
what does it mean to let go?
what is true?
how mush do I cause my own suffering?
am I truly happy?
who am I?
...there starts the path. we develop our way-seeking mind.

...who am I?

 thinking is a natural process, since not long after after our birth we have been thinking, so it is only natural that we should think. we should not stop thinking, the point of a spiritual journey is not to stop thinking. we should utilize our thoughts, as part of our human senses. a thought may arise from within, just as a cloud may suddenly take form in the sky before our eyes. when we see the cloud we can not will it to take form, nor can we force it to disappear. clouds follow the cycle of creation and death according to nature.
it is the same with thoughts. when one watches the inner seasons, suddenly there may be a thought arising, we should not try to suppress it or alter it, neither should we be bothered by its arising. we should notice it, acknowledge what the thought is, and allow it to pass naturally. moment to moment we should try to let things happen and simply notice how things take place within.
that is how we learn to let go. just as the cloud takes form and disintegrates without leaving a mark on the clear sky. while the cloud is in view, the sky is still present behind the cloud. in meditation, our mind, our nature is like the sky, clear and limitless. we train ourselves to through meditation to acknowledge the clarity of mind beyond the forms of thought.
thoughts may came and go but we do not forsake our mind to become the thought, just as the sky does not become the cloud. the thought is part of you, and has a place within but we should not identify the thought as our self. just as we do not call the cloud the sky.

...how do I let go?

as an athlete conditions their body to move to their will through practice and repetition, so does a spiritual athlete condition their mind. what one does in meditation is align the mind and body as one whole being, by following the breath, safely and peacefully in silence. when we follow our breath we are acknowledging our universal nature, and we begin to calm our thinking mind and let go into the unknown. in the focused concentration of an athlete, a thought will disturb the precision of action. over time, the athlete learns to identify with their body and mind in stillness, in silence, and that is the source of their power.

many people through history have taught the path of liberation from suffering and non attachment to self. by practicing meditation or mindfulness we develop the ability to see the mental habits which cause us so much suffering and confusion. we become the guard of the temple (mind), and oversee who or what enters through the doors (senses). we may see that for years we have allowed many enemies to enter, and that the temple may already be overrun by foes who have been terrorizing the residents.

after years of training in meditation we develop the strength of integrity and reclaim ownership of the temple ground. enemies may enter, but they will not reside.

when we calm the mind and align our body and mind, allowing things to be just as they are, senses in harmony with sense objects, we are truly ourselves, we let go of our thoughts, and we are able to live beyond harm, beyond thought. there is no One to harm.
