"We must offer no resistance to the challenges of others, because this is precisely what the collective ego desires."
Breaking out of old belief systems can take a bit of work, not just because you will experience internal resistance but because you may experience external resistance as well. This external resistance may come in the form of the collective unconscious of others. This can also be called the collective shadow.
This collective shadow is unseen by anyone who participates in it, even the givers and the receivers. This is the subtext that governs are interactions with others. What is happening is the other group "egos" we participate in: family, friends, and society at large do not like it when this group ego shrinks. As you begin to wake up, the shrinking of your ego is a threat to these other entities.
The collective egos respond through the collective shadow, using whatever tricks necessary to "get us back." Again, our family, friends and others do not even know they are doing this or why they are doing this.
If we have done our internal work of grappling with our own shadow, then we are prepared to handle the resistance of others. How are we to respond to challenges to our new way of Being? We are to respond with love, kindness, gentleness and compassion. We must offer no resistance to the challenges of others, because this is precisely what the collective ego desires. The ego grows through dissension, bickering and fighting. It shrinks through love and selflessness.
The irony is the more that we offer no resistance, the more resistance may come at first. An attempt to listen to others opinions or even confrontations without reacting will come across as "holier than thou." At its core, the collective ego does not understand freedom that comes with detachment. It is not fair to the ego that we can live a life removed from guilt, shame and fear. The collective ego wants to absorb our ego back into itself.
All that we can do on this path is be prepared when this resistance comes. Even when you have made great progress internally, you may encounter resistance in your interactions with others. We can disable this resistance through not reacting to it and loving others. Others, through their collective egos, do not have power over you anymore. They are a part of the forms of this world. Connect with those who challenge you through the Formless, see them as Spirit, and your love will transmute any resistance into harmony with others.
