Unfortunately, over time, people redefined 'soul' oblivious to the fact that it thus overemphasized on actualy what it doesn't count: 'the sabstance'. What counts: 'immortality' eventualy went under the bed! So I warm the floor by re stating the truely meaningfull and original definition of 'soul'.
SOUL: The immortal part of us.
The other common definition? Not very smart! It emphasise on ill-defined, mis-defined or downright undefianable concepts: immaterial, incorporeal, energy. Eventual, anything intangible, came to be dubbed 'soul'. Afteral 'immaterial' etc merely negates 'matter' and doesn't tell us what it is that is not matter. The lunacy reaches climax when abstract concepts such as thoughts, feelings etc came to be labeled 'soul'.
In the proper definition, if one can show that the body is immortal, the he establishes that soul IS the body! In the popular, misguided notion, incoporeality is worshiped for its own sake!
