Engineering without science, you have planes falling;
Science without engineering, you have paper planes.
Practice without Dharma, you practise blind;
Dharma without Practice, it’s a nice theoretical idea.
Hope 2019 has treated you well. Hope you have treated 2019 well.
If not, try again next year.
PS: One could also say that there’s no engineering without science, just as there is no real practice without Dharma.
