Perception can be defined as the whole of stimulus that create reality around us and shape our general response depending on what we see, feel, smell or hear; most of the time as we grow up, we are taught on how to respond to “negative” stimulus, as to ensure our survival and continued existence, but as a recently educated being in the path of buddhism, most of these reactions you come to learn, are not necessarily the most appropriate, and even your “perception” of reality might not be the most accurate.
Early on your path of buddhism, you come to learn that in life there are 3 absolute truths in life, which may cause you grief and suffering when trying to negate or fight agaisnt them; impermanence, change and your own sense of self -these roughly cited and presented, for simplicity-. Impermanence teaches you that nothing in life is permanent and hence, trying to hold onto things is futile -the key to happiness is actually learning to enjoy what you are given- and accepting change as a fact of life, supported by the final notion that everything you do, big or small will always affect someone.
When it comes to SL, perception and how you present “reality” to others may vary, -the same may apply to the 3 fundamental truths- but it is all there; haven’t you ever marvelled at the concept that no matter under how many alts people may try and hide to bend the truth and alter your perception, the real person always shines thru? There’s always so much you can do and struggle to hide the truth, specially shielded by the “anonymity” our beloved virtual platform may offer, but in the end, your true self, that which makes you an unique human being will always be there.
That would be why I have come into the habit of not turning anything presented to me by life or others as absolutes, specially so when it comes to SL, there is always that which you are shown, and what truly lies beneath.
