Used responsibly, LSD is a phenomenal tool for introspection and "thinking about things from a higher plane". It's hard to describe to anyone who has not tried.
Remove your consciousness from your life experiences, everyday minutia, your body's senses, and politics/history pegged to a timeline, and so on. Freed from these tethers, incredibly insightful things can be realized for the first time in the mind. After you come down, and you remember the experience, you will never view the world the same-old way again, but will process subsequent life experiences from an additional, fresh, and wholistic view-point. It is a marvelous eye-opener.
Once you've "climbed the mountain" of a strong and positive LSD trip a few times, you will no longer need to take the drug to "get to that place", and to see things in this additional, new light. It is a breathtaking experience and changes your perspective forever. Well, for decades, at the least.
