The Shijie practice in Taoism is an esoteric technique that allows an adept to leave their physical body and travel outside of it, which can be interpreted as a form of liberation or release from the constraints of the physical world, including the family lineage system. This practice is not directly mentioned in the search results, but the concept of liberation in Taoism can be seen as a way to transcend traditional social structures such as the family lineage system.

The family lineage system in traditional Chinese culture is deeply rooted and has significant social implications. Practices like filial piety and ancestral worship are central to this system. However, the Shijie practice, by allowing for a form of spiritual liberation, can be seen as a way to step outside of these traditional roles and obligations.

While the search results do not provide a direct link between Shijie and abstention from the family lineage system, the broader context of Taoist practices and beliefs suggests that there is a potential for individuals to use such practices to distance themselves from traditional social structures. This could be seen as a form of spiritual abstention from the expectations and obligations associated with the family lineage system.

It's important to note that the interpretation of Shijie and its implications for the family lineage system can vary, and this answer is based on the available information and the broader context of Taoist beliefs and practices. For a more detailed understanding, further research into specific Taoist texts and practices related to Shijie would be necessary.
