I don’t know how… Basically, I’m somewhere in between “I hate the world” or “I’m indifferent towards it.” But the whole of reality, it’s just it. It’s stupid. It is out there. I don’t care about it. Love, for me, is an extremely violent act. Love is not “I love you all.” Love means I pick out something, and it’s, again, this structure of imbalance. Even if this something is just a small detail… a fragile individual person… I say “I love you more than anything else.” In this quite formal sense, love is evil.” ― Slavoj Žižek Original piece: https://theunhappyman.substack.com/p/write-through-love {Podcast} Spotify: https://open.spotify.com/show/4ryEqjut4r6SMtfxLdM1Le Anchor: https://anchor.fm/rahul-samaranayake {Website} https://rahulsam.me/ {Social Media} https://twitter.com/trsam97 https://www.minds.com/trahulsam/ https://www.linkedin.com/in/rahul-samaranayake-981a9315b/ https://trahulsam.medium.com/ https://www.instagram.com/name_is_rahul/ Facebook Group: https://goo.gl/JoL9CA If the ideas I discuss in this channel evoke your interest, consider visiting https://theunhappyman.substack.com/ Copyright Disclaimer under section 107 of the Copyright Act 1976, allowance is made for “fair use” for purposes such as criticism, comment, news reporting, teaching, scholarship, education and research.

The promise of love from others carries with it the hope of curing our anxiety and inner void. When this hope is taken away, we are essentially deprived of our own selves. In the disillusionment of anothers promise of love, we come to realize its true nature — love is revealed as an illusion, a facade concealing its inherent absence. Love has always been empty at its heart; its just that before our disillusionment, we could believe in the illusion of a fully present love, while denying its inherent void. - Dr Julie Reshe, SCREAM PAIN LOVE Watch the full podcast here: https://youtu.be/-x-MhB_2m44?si=7nxBgmhae4hO-9GF {Podcast} Substack: https://rsampod.substack.com/ Spotify: https://open.spotify.com/show/4ryEqjut4r6SMtfxLdM1Le Anchor: https://anchor.fm/rahul-samaranayake Available on other platforms at https://link.chtbl.com/PDBAf9Zd {Website} https://rahulsam.me/ {Social Media} https://twitter.com/trsam97 https://www.instagram.com/name_is_rahul/ https://substack.com/@trsam/ https://www.linkedin.com/in/rahul-samaranayake-981a9315b/ {Images & Videos used} Thumbnail: Head by Head by Edvard Munch (1905) If the ideas I discuss in this channel evoke your interest, consider visiting https://theunhappyman.substack.com/ Copyright Disclaimer under section 107 of the Copyright Act 1976, allowance is made for “fair use” for purposes such as criticism, comment, news reporting, teaching, scholarship, education and research.
