It will be such a broad question you can say whatever as long as it is relevant to your text, i.e. process of discovery might allude to its catalyst (curiosity/wonder/necessity), the circumstances (surprising/unexpected/confronting/provocative/rediscovery of something concealed/hidden/forgotten) and its impact (refreshing/meaningful/stimulate new values/perspectives of oneself, others and world/renewed understanding). You can say discovery process is slow and multi-faceted as long as you have the textual evidence to back up what you are saying.
