I am no expert in Freudian psychology. No doubt if I were I could write a book just talking about these three aspects of self and telling you how Freud's own thinking on them developed. But I am not and I cannot. It is interesting, however, that our common everyday use of the word ego has parted company somewhat with Freud's theory. Ego is the Latin word for I, so we tend to make the word synonymous with our sense of I-ness. What in non-dual tantra might be called ahamkara.
The word ego is tossed around as if it is something undesirable. As such it is being confused with another term, egotism, which is the state of being excessively self-absorbed. So when we say something like "Oh, he has such an ego!" in that judgy, perjorative way that we do, we are really saying that he is egotistical, that is, self-absorbed. And what a terrible way to be, poor person!
Of course, the self in which this poor person is so absorbed is not that capital S Self that is used as a descriptor for the Universal Consciousness, beyond concept, which is therefore impossible to describe. No, it is the small s self, I, me. It is a thought and a bunch of ideas, beliefs about what "I" am.
Note well that it always another person, never ourselves that we hold this belief about, that they are self-absorbed and egotistical. Yet this belief about another is surely created as a reaction to another belief, that things should be a particular way which make me feel comfortable and this person is in someway violating that and therefore must be wrong, namely, they are self-absorbed. Is it not our own self-absorption that created a belief that things should go our own way that leads to this other belief that another person is self-absorbed.
The message here is that it is all belief, all thought and you just cannot trust it to be in anyway true.
Maps of the territory
Freud's theory of Id, Ego and Super ego is nothing more than a map or model of the mind and sometimes perhaps its view is useful, but there are other views which might serve us better, sometimes. It is like Google maps. We can see the map, the street view, perhaps we might even be able to see a satellite image and so forth. We use the view that is most useful.
The yoga tradition has also mapped the territory, in many ways, with the purpose of pointing us beyond the mind to the essence of our true nature.
What do we really know is true?
This is the essential question on the spiritual path. In many ways it merges into this other big question:Who am I?
In answering Who am I? we might come up with all sorts of labels and beliefs. A name? That is a label. A place in a family, wife, husband, mother, father, sister, brother? Are they not labels too? Can a label be true? Do they tell you what is your essence nature?It can be scary as you begin to peel away all the labels, all the ideas, all the beliefs and begin to recognise them as being quite unreliable, things that in fact feed your own self-absorption. The pathway to Self-absorption is destructive. Big S Self-absorption, which is to rest in your essence-nature, cannot co-exist with small s self-absorption. The moment we fall back into small s self-absorption we are forgetting our big S Self.
Small s self is quite worried about being destroyed and is as adaptable as a super-virus to any attempt to undermine it. But the thing is that it is the absorption that we are overcoming in order to abide in our essence nature. Then we can utilise the small s self to navigate life without being pulled into absorption, simultaneously knowing our true Self, which is so much more!
Practice
If you are ready for this scary journey here are some things you might do.Practice iRest® Yoga Nidra meditation. Within the iRest protocol you are invited to examine your beliefs, pair them with opposites , notice the emotions that co-arise and trace them into the feelings in the body, pair them with opposites and ultimately recognise that neither is completely true, opening the way for experiencing that which is true.
Another practice is to take a notebook, a pretty one is best, one that you could really value. In it write everything that you think is true about yourself , others and the world. Putting it out there can help you find objectivity and might help the process of taking it into meditation and really examining its veracity. When it is full find an opportunity to ritually burn it. With it burn all attachment to those beliefs.
