GOLDEN SUNRISE
The departed soul has already proceeded for next journey. Though you can request VK in your own words to seek the answer, i personally feel it should NOT be done. (Unless it is required for some legal or such formalities)
Sharat Sir guides us to move ahead in life. Maybe your friend is holding guilt in his mind so he wants the answer. Even if the answer is sought, it may invite more guilt of not being able to rectify those reasons and the person may feel more helpless.
Better way would be to help the person to get back to his normal life. You can charge his water with BACH FLOWER RESCUE REMEDY , MOOD UP SERUM and BALANCE SERUM for at least 3 months. You can charge the main drinking water tank of his home. This will benefit all members staying there and help them to cope up with the past.
Please check VK Tip 76
You can send ALL CLEAR SERUM to his questioning thoughts about this event or request RELEASE GRIEF to VK for him.
If these questions are coming from relatives or friends to him, you can send him SHIELD OF 7 RAYS with intention that he is protected.
