What is Nirvana and Parinirvana? 

Can you say how the universe came into existence

@@aritra834 Hello. Universe and Cause and Effect are intertwined. Cause and Effect are "in" the fabric of the Universe, in a way movement is "in" the fabric of a wave, and in a way movement "is" wave. When we say "How" the Universe came into existence, we mean "What Caused the Universe?", which means "What Caused the Cause and Effect?". Cause and Effect and Universe is eternal. Universe undergoes infinite Contractions and Expansions. And it's nature is determined by the collective Karma or the Human beings who take birth in it. In terms of "what exactly happened", the Universe has a fundamental nature. Nothing in it has a self essence or "exists by its own nature and essence" but "everything emerges in pairs of opposites and gains their essence and nature from the opposite" (Lord Nagarjuna). This is called Dialectics in modern sciences. And you can intuitively see it that your body doesn't change by itself it's changes are also induced by external elements - in other words if everything outside the body somehow ceases to change and freezes in time, your body will not change. Blood itself will stop flowing (as pressure changes will become impossible). You can read more examples of Dialectics in Nature for better intuitive grasp. Now, the Universe and things (objects and beings) that exist in it undergo this infinite interrelatedness without ever even being aware of it. We know from science that at the speed of light time freezes. It is this property of light that is also same in the universe that it's infinite interconnected influences everything in it even if it's at further distance than light with each other (say two planets further distant than speed of light - their influence on each other is occurring at a speed faster than light). This means universe has a property "akin" to light (where it's interconnected ness transcends time). This is what I conjecture is referred to "infinite luminosity" being the "true Buddha nature of all minds". Universe also has a psycho - physiological nature. What you eat is present outside you - so your desires and universes psychology is intertwined as well. In infinite luminosity dimness appeared, in dimness darkness appeared, and different variations of dimnesses formed "compartmentalizations". With compartmentalizations and interdependent interconnectedness (this is this way because that is that way, if this changes that changes too). The compartmentalizing agent is the "individual mind" (it has no self existence it exists only because of compartments, yet it experiences itself as self working - an error - called ignorance in Buddhism). This is the first condition of "how it came about". From fundamental elementary compartmentalizations also at the same time began elementary sentient "minds". It is this "I - mind" that undergoes rebirth. Not the infinite luminosity, the actual universal "mind". The compartmentalized mind forms the 5 core elements. With its coming into being comes space. In space, with subtle fluctuations, comes air. With air frictioning against itself and space comes fire. From fire and air interaction comes water. Water as it cools down becomes heavy and forms earth. These five elements emerge from the "compartmentalizing mind and compartments fluctuating" against each other - starting with subtle and then taking gross forms. It is also five we have five senses and not six and seven - as senses are interdependent on the five core elements. Example - No fire no light no eye sight. This also leads to formation of planets and geography. Earth element when heated turns to water fluid, showing earth is nothing but water minus fire. This also then goes on into the six realms of existence. For example too much anger and lust causes fire element increase and also leads to hell. Equanimity and wisdom leads to "lightness and tranquillity" and it "moves up" and leads to subtle Heavens. This is "on the go" brief. If you want books to study from, I can recommend. But the gist is given Thanks you 🙏

@@aritra834 There is a quote in Tibetan Buddhism - The world doesn't have objects in motion. The world "is" motion. Take example of a wave in still water. When water is still, there is no wave. Wave exists ONLY through movement in water. Some of the water moves faster then the rest - is all the water moved at exact same speed there still won't be any wave. Also, when a wave occurs as you throw a stone in still water, you might "see" that some of the water is moving in circular ripples while other parts isn't - hypothetically if the entire water moved at the same speed there would be no waves (just how if you'd shoot a heavy ball at a industrictible object it would move all together and have no waves) - so there is relative motion and Interdependence without which wave (analogically equal to an object of noun in world). And "in reality" the water "on which" the waves appear, the underlying still water, is still in movement - it sinks a little - so only because of its relatively less vs relatively high motion of waves, we see waves. In other words wave is a "clash" of energy - no clash (equal energy movement in one object or universe), no wave would emerge. And same applies with clashes of waves. This is exactly how our world also is at a physics level Objects are "frozen" energy, frozen only through "interdependent influence" of each other. So there are two parts when you study it - one is the physics part (what the world really is if we could see it perfectly) and other is existential truth (the truth that emerge from it - no self arising or self dependent existence of any phenomena though they "appear" to be self functioning, infinite inter relatedness). It is just the "individual mind" latching to "causes and conditions". Like wave thinking it is a "separate entity" from the water and has a "independent nature and essence". Infinite luminosity is in some measure compareble to water. When still it was all that was there, when moving it is all that there is (ultimately - by ultimate one means logic cannot further attribute it to another cause or root essence). The individual mind can be compared to a wave or ripple thinking "ah, I am wave, fast moving all eroding", but it's entire existence through and through (in all ways - what is it made of, what forces have caused it fluctuation in still water - wave is merely a "off setting" of all that is already there - the laws that cause waves weren't made by wave, they existed in still water itself) is it's source - water itself. In our samsara the Infinite Luminosity is "intuited" through infinite Interdependence. And experience and attained through practices. Else we keep moving in Samsara undergoing waves of delusions. Why does Samsara exist at all? It exists because under infinite luminosity there is no "condition" to prevent fluctuations, as conditions themselves need infinite luminosity to function, and hence would themselves be infinite luminosity itself in their ultimate nature. Hence this "ignorance" or lack of inferring agent in some sense that brings it all into "existence", while the essential underlying fabric remaining ever present and infinite. Thank you 🙏

@@aritra834 We are also advised to not stay lost in the jungle of Metaphysics. If we can "sense" that what Buddha is saying makes sense but right now we are not fully able to learn it, we should always make Naianfo our primary practice 🙏

@@hobosapien7735 but where the buddha says about universe

How you know buddhism is real ??

You can perhaps watch the videos here to gain more understanding: What is a Buddha ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ke7vW68ea3M.htmlsi=eM3Jc8YxqIgqi4vB What is a Bodhisattva ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1bQq7Yc8NgI.htmlsi=y3s1ZQ5-bH5ICdWP (And yes the Buddha is everywhere - see three bodies of the Buddha - Dharmabody) Amituofo.

How would the answer help you on your path to enlightenment? Does it matter what would be the cause? I have heard about some sutras mentioning it, but don't know which ones. I recommend you to ask buddhists more focused on general Mahayana. Jiawen teaches mainly sutras important to Pure Land Buddhism.

@@mirror1279 this will help me decide that wheather I am following the correct relegion or not . When we look at the universe we see design. Every designed thing jas its designer. So when buddha became enlightened why didn't he tell us about that designer. 🤔 that makes me think that when amitabah and other buddha attains nirvana what happens to them . Where their consciousness go
