Who are we? For the Master, I am a Servant,
For the Teacher, I am a Student.
Frankly, the I, you, or we are closely associated with the process of becoming in the domains of existence. The mind and body would evolve depending on the conditional phenomena; just as ice, water, and steam appear ephemeral in relation to the orientation of H2O properties. Eventually, the phenomenon exists as this or that depends on the observers. It’s like describing the same elephant by different blind people, namely a blind person can tell that an elephant looks like a tree trunk; another blind man would describe an elephant as a snake.
Hence, a simple and straightforward answer would be: “I am what I am”. The applicable principle: “If you think this is who I am, then I am”, and “If you know this is what I am, then I am”. At the end of the day, the phenomena that happen are very much linked to the consciousness that perceives them. This is what the conventional reality is all about, i.e. the final conclusion is subjective-cum-relative and varies from one observer to another. Likewise, in respective circumstances, you can be named as a son, a father, a preacher, a student, a Caucasian, an American, a skinny man, an old man, a stranger, and so on. Just like a proverb, “One man’s meat is another man’s poison”.
