@G77777 ji, yes you can keep VK in pocket or purse or handbag as you are comfortable.
you can wear it also, to keep VK aside is only because of tendency of our mind. Mind keep thinking continuously and chattering on its own,
so does it mean if you place a request to VK and energy should be given atleast for 30 minute (VK gives automatic). but there comes another thought so VK will start following the new one request.
However if you can keep observe your thoughts then wear VK as usual.
