Alternative Seal is also called by some schools as Indirect Resource but the actual term in Chinese is Pian Yin (偏印). It’s counterpart is known as Zheng Yin (正印) or Righteous Seal or some schools call it Direct Resource.
Resource is the element that produces the Day Master in the 5 elements of Production cycle but due to the Yin – Yang polarity they are accorded the title of Righteous (Zheng) and Alternative (Pian) accordingly. In some school of thought, Improper Resource is said to be less preferred than the Proper resource since Zheng usually gives a more upright, moral and good side picture while Pian usually gives the more scheming, cunning or less law abiding image. Pian 偏 in Chinese usually brings about the idea of an “illegal” connotation.
However, in my opinion this thinking is very regimental.
