The famous Biblical dictum "Love your neighbor as yourself" is generally explained to mean that you must love yourself first before you can love your neighbor. This interpretation rests on the tacit assumption that you and your neighbor are separate entities. But what if that assumption is nothing more than an illusion of the ego?
I have come to realize - first conceptually, then experientially - that this is indeed an illusion. If neighbor and self are not truly separate, then love is not a relation but a recognition of unity. The task is to liberate ourselves from this illusion of the individual ego.
Of course, this is easier said than done. I see at least two formidable obstacles we must overcome for such liberation. The first is our identification with the physical body. If asked "Who are you?", few people will answer directly "I am the body", yet many assume it unconsciously. From this false identification it is only a short step to the illusion that each of us is a separate entity, delineated by a physical body.
The second, more subtle obstacle is our language. It is supposed to serve us, but in fact many people are controlled by it through labeling - an unconscious and automatic mechanism that interprets every physical body as a separate entity. These labels include, first and foremost, names, then family background, education, profession, social status, and so on. In this way language constantly reaffirms separateness through subject-predicate-object structure. Even "I am X" is a trap.
Conceptual labeling through language is not limited to individuals. We are not only labeled collectively by others but also label ourselves collectively. This is the illusion of the collective ego. Even "mankind" is a subtle example of such labeling.
Had Zamenhof encountered the experiential teachings of Chassidus, he might have seen that the unity he longed for was already present beneath the illusions fostered by language.
My hopefully constructive criticism of Esperantism is based on my own years of involvement. When I left, I explained that I did not "discriminate" against Esperanto, but simply lost interest in languages and linguistics after realizing that language often serves as the gatekeeper of the egoic mind.
Sadly, I saw this dynamic also among (some) Esperantists when I heard a rumor that I had left because I discovered what they labeled a "fanatic Jewish sect" - namely, Chabad Chassidus. I also witnessed how one important international organization demonized an entire national association by labeling it collectively. Zamenhof longed to dissolve borders, but some of his followers erected new ones in his name.
All identities, whether individual or collective, are ultimately illusions of the ego. Seeing through these illusions means shifting from self-consciousness to Divine consciousness - recognizing that all creatures are Divine sparks, parts of the Universe, like waves in the ocean.
Chassidus does not end with dissolving the self into oceanic unity. Its ultimate aim is to return the self - body and ego included - as a sanctified vessel for Divine presence.
