2 points I gathered from this article which I can apply to my practice:-
1. When consulting divination and advice from the oracle, we should always follow instructions to the tea.
The status of the oracles are defined by the deity they took trance of. We are not talking about ANY oracle here but an oracle (the Panglung oracle) who took trance of an Enlightened Protector such as Dorje Shugden. During trance sessions to consult for divination, the DS oracles were invited by the monasteries like how they would invite a High Lama to the throne which is placed in front of the monastery's main altar. Upon the arrival of the oracle, music and instruments will be played. Everyone in the monastery will rise. Abbots and high ranking monks will make offerings to Dorje Shugden via the oracle.
These are the signs of the oracle's status this article is talking about here.
If war has been carried out as per DS's instructions via the oracle, it would have been made difficult for the Chinese to invade Tibet. Due to disharmony and disregarding the advice, Tibet has fallen in the hands of the Chinese. In our everyday life, we should always be harmonious and be at peace with everyone around us.

2. We should put full TRUST look upon Dorje Shugden as an Enlightened protector and not some common protector who can help us with our spiritual path.
Dorje Shugden has single-handedly saved the whole culture and Vajrayana Buddhism. Without DS's foresight and clairvoyance, all of Vajrayana Buddhism along with the erudite masters and monks may have been lost. DS has foresight and clairvoyance because of DS's past incarnations such as Tulku Drakpa Gyeltsen, Panchen Sonam Drakpa, Duldzin Drakpa Gyeltsen had clairvoyance.
Many Mongolian royalties were loyal supporters of HHDL and has made vast amounts of offerings. When HHDL fled Tibet, he must have left billions of treasures and sacred text behind in the Potala Palace. This shows how much trust HHDL have on Dorje Shugden to leave everything behind and put the fate of his life to DS. We too can surrender our little treasures and fate to DS to bring us to a better place in our future lives.
