This is the second part of an account that begins at Hexagram 51
The translation I use most actually translates Hexagram 16 as 'Providing For', which fits well with its theme of caution and preparation. I understood this as telling me to prepare thoroughly before launching my business' website - to marshal reserves of emotional strength as well as all the purely practical measures. 'Installing feudatories to move legions' suggested the need to think about site promotion if I was to have any visitors! And the call to double the gates and install night watchmen made me think about security (credit card, emails etc). (Very modern oracle!)
With the benefit of hindsight, I think that - having been made nervous already by Hexagram 51 - I missed the other half of the message, which was 'Enjoy it!'. But when I did eventually build and launch the site (and I was right not to start it at the time when I first asked), there was no shortage of enthusiasm to go with the upheaval.
