If you have MORE THAN ONE VK, give request to each VK While wearing they both may follow your intentions. So for specific requests to each VK, place a request to each of them separately. You can give the same request to more than one VK for the same issue, this will multiply the energy. You can also choose to give different requests to different VKs.
If you have more than one VK, either wear them in different hands (if you wish to wear 2 VKs in the same hand), or wear a non-VK bangle between the 2 VKs if in the same hand. You can also wear one VK on your wrist and another one in a chain in the neck.
(The smallest VK is only 3.3cm, I lovingly call it Chotu VK. This size can be worn conveniently in a chain in the neck or can be carried easily in a wallet.)
NOTE: Each VK is a separate unit, so you can either give the same request to each of them one at a time or give 2 different requests to each of them separately.
