The Immune System, Atman and Brahman

Siddhartha Mukherjee is an excellent writer. I’ve loved both of his earlier books, and the latest one, The Song of the Cell, is just as great as the others. The immune system, as we know, fights and kills invaders. But that raises a new question: how does the body which cells are the “self” v/s which ones are the “other”?

 

Before he answers that question, Mukherjee gets into Hindu philosophy. Why?! What’s the connection?! Technically, there’s no connection. But if you’re as great a writer as Mukherjee, well then…

 

Western philosophy, he says, differentiates the body from the soul, us from them. Whereas Vedic philosophy does the opposite, he writes:

“(It) welcomed the erasure of the individual self and its fusion with the universal… The self was an ideal fusion of atman and Brahman.”

And adds:

“The phrase ‘Tat Twam Asi’ – ‘That you are’ – permeates the Upanishads and is an expression of the boundless self that permeates not just a single body but also the cosmos. You, the self, the Upanishads proclaim, is permeated and penetrated by That, the universal.”

 

The immune system, obviously, does differentiate between the “self” and the “other”. Or as he asks tongue in cheek:

“Why else would a sponge go to such lengths to limits its fusion with another sponge to form a blissfully boundless cosmic Brahman sponge?”

 

I’ll end this blog here so it stays pure and philosophical. (If you want the answer to the question as to how the immune system differentiates which cells are the self and which cells are the outsider/invader, wait for the next blog).

Student of the Year

As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
