Have you seen "what is spirituality" topic on this Forum?
To me spirituality is equivalent to developing the abilities of the MIND. Specifically, the ability to make CHOICES and learn from their consequences. Intelligence is the facility of the MIND that enables us to make CONCLUSIONS from our mistakes and modify our choices and motives. Non-intelligent people keep repeating their mistakes and complain about their bad luck.
It is not WHAT we do, but WHY we do it. Not apperances, but what is BEHIND them is the most important.
Consider this. Begger may rescue a child in the expectation of the material award. Scientist may study Atom, because he truly wants to Understand the Designer of the Universe.
I haven't heard of any real scientist who deliberately uses weapons. Don't POLITICIANS manipulate people to kill one another?
Everything, TV, media, atomic energy, kitchen knife CAN be misused against people. MOTIVES and conscious choices make all the difference. Spiritually evolved people just make different CHOICES because they have different MOTIVES and different PURPOSE in life.
No matter what you do in Life - farming, raising family, writing books or making inventions - focus on MOTIVES for your choices. Motives make all the difference.
