I want to know the answer to the following question:
What was the first skill Gautama learnt?
All the background I'm provided with is that "He devoted himself to anapanasati meditation, through which he discovered what Buddhists call the Middle Way (Skt. madhyamā-pratipad): a path of moderation between the extremes of self-indulgence and self-mortification.[web 2][web 3]". Is that enough to answer the question?
Answer: yes
