The most venerable Vimalaprabha has said that regardless of whether this period lasts one hour, two hours or one day, this state and the state of a buddha are no different. In other words, the Buddha's state and the state before the existence of samsara, as well as the state of waking up from fainting after death, can be seen as completely inseparable. This is because, through Dharma practice, a buddha has completely removed all afflictions and they no longer arise. Although ordinary people are able to experience this particular state for a moment, without practicing Dharma they are unable to stop the arising of afflictions altogether. This state only remains for a short while for ordinary people; subsequently, a new cycle of samsara will begin while a new bardo is created. The very first moment of the bardo arises from this state. Thus, this is one beginning of samsara, and this state is exactly the same as the process of the farthest beginning of samsara and the dawn of life.
