Aadi Swathi 2025 - திருவல்லிக்கேணி திரு தெள்ளியசிங்கர் புறப்பாடு

இன்று 1.8.2025  ஆடி ஸ்வாதி ~ திருவல்லிக்கேணியில் திரு தெள்ளியசிங்கர் சிறிய மாடவீதி புறப்பாடு கண்டருளினார்.  கோஷ்டியில் பேயாழ்வாரின் மூன்றாம் திருவந்தாதி சேவிக்கப்பெற்றது.   

 

Fire has been a core principle in most  traditions, cultures and religions across the globe. Lighting a Lamp is considered sacred -  a daily ritual,  a key step taken on the path of light, fire, and grace.  Lamp is reverred and the flame not only provides light but also enlightens !

Away, there is Electricity.  We use light bulbs every day: at  homes,   offices, stores and more.  When we talk about a “regular lightbulb,” we mean an incandescent bulb, the type that’s been around since Thomas Edison patented his invention in 1879. An incandescent light bulb, is an electric light with a wire filament that is heated until it glows. The filament is enclosed in a glass bulb that is filled with vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.

Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely.  Incandescent bulbs typically have short lifetimes compared with other types of lighting.   There reportedly have been inventors prior to Edison of General Electric.  Thomas Alwa Edison's version was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum and a high resistance that made power distribution from a centralized source economically viable.

For decades, 100-watt incandescent light bulbs have lit up hallways and bedrooms; 60-watt incandescents have shone softer light from reading lamps and closets. But incandescent lights are inefficient, waste lots of energy as heat, and have shorter lifespans than fluorescent lamps. Recently, more-efficient compact fluorescent (CFL) bulbs have become popular alternatives. Where incandescent lights last an average of around 1,200 hours, CFLs can last 10,000 hours  !!  Unfortunately, CFLs contain toxic mercury that makes them potentially hazardous and a pain to dispose of.

Then came LED – not exactly of recent origin.  LEDs offer the advantages of CFLs – lower power consumption and longer lifetimes – without the downside of toxic mercury.  So these days, none uses those gundu bulbs, replaced by LED bulbs.  Technically, LED bulbs aren’t bulbs – LED stands for “light-emitting diode.” They’re tiny semiconductors (diodes) wrapped in plastic to protect the elements and focus the light. LED do not have filaments and function completely different. When a current passes through the electrodes and semi-conductive material, it emits visible light, or a photon.

It has been over a century since the English engineer H. J. Round first discovered the phenomenon of electroluminescence, a breakthrough that led directly to Oleg Losev’s invention of the first light-emitting diode (LED) in 1927. LEDs are inherently flexible, allowing for a wide range of design possibilities. From bendable strips to ultra-thin panels, LEDs can be incorporated into virtually any space. This flexibility enables more creative and customized lighting solutions for residential, commercial, and industrial applications.  Human-centric lighting (HCL) is a growing trend that focuses on the biological and emotional impacts of light on humans. By mimicking natural light patterns, HCL can improve mood, enhance cognitive function, and regulate sleep-wake cycles. This trend is particularly relevant in workplaces, healthcare facilities, and educational institutions.

The future of LED bulbs is bright, with advancements focused on higher efficiency, improved color quality, integration with smart technology, and enhanced sustainability. Expect to see more sophisticated smart lighting systems, human-centric lighting mimicking natural daylight, and wider adoption in various applications, from homes to industrial settings.

Moving away from such Electric lights -  for us it is the divine lights that leads to salvation.  We follow the path of light to move to the lotus feet of Sriman Narayana.

தமிழ் தலைவன் என்ற புகழ் பெற்ற ஸ்ரீபேயாழ்வார் நமக்கு உரைக்கும் பாசுரம் : 

உய்த்துணர்வென்னும் ஒளிகொள் விளக்கேற்றி,

வைத்தவனை நாடி வலைப்படுத்தேன், - மெத்தெனவே

நின்றானிருந்தான் கிடந்தானென்னெஞ்சத்து,

பொன்றாமை மாயன் புகுந்து ! 

மனத்தினாலும் அறிவினாலும் உய்ந்து உணர்ந்த விவேக உணர்ச்சி எனும் மாசற்ற தீபத்தை ஏற்றி, ஸ்ரீமன் நாராயனான எம்பெருமானை தனது இதயத்திலே வலைப்படுத்தி தனதாக்கிக்கொண்டால், அவ்வெம்பெருமான் குறை ஒன்றுமில்லாமல்  ஹ்ருதயத்திலே குடி புகுந்து, அமைதியாக, முதலில் நின்று, சற்று பிறகு,   வீற்றிருந்து அதன் பிறகு அங்கேயே  பள்ளிகொண்டருளினான் ~ என்கிறார் தமிழ் தலைவன் பேயாழ்வார்.
