When your thoughts are clear and positive, VK will follow you anyways.
Place a request 3 times; the request goes from 3 levels… from your physical level, mental level, and spiritual level. If VK does follow your request just by thinking once then VK does not work for you because we human beings usually think 60000 thoughts per day or on an average one thought per second. Placing a request 3 times protects your VK to follow your every thought and continually work on your placed request. NOTE: Please remember one-time request placing means repeating a requested sentence 3 times.
Sometimes the wish is manifested just in a single request because it comes from your deep thoughts or directly from the spiritual level or needs very less energy to be manifested.
Sometimes the wish is manifested even without any request because VK is an intentional tool, it works on your clear and positive thoughts in your conscious or subconscious mind. Generally, it happens when you and VK are connected very well with each other.
