I think that lsd leads people to realize the importance of love over other petty things like power and money. Therefore, indirectly, you could easily make the claim that lsd leads to love, or at least an increased appreciation for it.
i have never felt so much as i have on 10 hits of acid. i saw gods love and it was the most pure unconditional love there, and overwhelming compassion for ever single thing. me, you, a planet, a bacteria, and an atom all get the same incredible amount of love. the most amazing part was becoming this love, i had compassion for every single atom on my body, for every friend and family member i ever known, for every piece of the universe there was an unearthly deep love, and i didn't have to try, it was flowing out of me. love and peace!
ya know whats phenomenal that i don't really experience much anymore, it is getting the sensation of every emotion in one. i really clearly remember this from my first mushroom trip, being extremely happy and extremely sad and everything else in between, and all at the same time, and also at the same time i could see what i was feeling. it was such an indescribable feeling, i knew i wouldn't ever truly be able to describe that to anyone. and i realized that your brain had a deeper level of thought that was practically boundless, you just had to unleash it. i have never really felt that same intensity of feeling since then. most the time my normal feelings are just increased, or i have strange acidy type feelings, but not like that feeling of every feeling, that was just amazing!
