Mars in in the 8th house in Taurus and Neptune is in the 2nd house in Scorp. Thanks.
This means there is a connection between your strength (Mars) and your idealism (Neptune), the two are inherently linked. Your strength will be activated by dedicating it to a higher cause (Neptune), possibly helping others or doing something for society as a whole.
In some ways this is similar to the placement of mars in pisces mentioned below.
