Guard Your Mind- Don't Follow Blindly. Question and Investigate First

We are constantly bombarded with lots of information from newspapers and advertisement that try to influence our lives and thoughts. 

Advertisements like to show people are happy because they own luxury items or you need to accomplish certain things to be successful or that loneliness is bad for health. Ironically, it was through quiet contemplation that Buddha became enlightened under the Bodhi tree. Instead, one should guide their minds from these influences. Question these information and investigate by questioning and from your own experiences. 

Kalama Sutta, Buddha had the following advice to the people from the town of Kalama  who seek his advice as they had received conflicting opinions and advice from the different 'holy teachers' on how to be happy and would like to know which teacher was speaking the truth.

Do Not Accept Any Doctrine From Reverence, But First Try it as Gold is tried by Fire.

From http://www.ling.upenn.edu/~beatrice/buddhist-practice/kalama-sutta.html

The people of Kalama asked the Buddha who to believe out of all the ascetics, sages, venerables, and holy ones who, like himself, passed through their town. They complained that they were confused by the many contradictions they discovered in what they heard. The Kalama Sutta is the Buddha's reply.

–	Do not believe anything on mere hearsay.
–	Do not believe in traditions merely because they are old and have been handed down for many generations and in many places.
–	Do not believe anything on account of rumors or because people talk a a great deal about it.
–	Do not believe anything because you are shown the written testimony of some ancient sage.
–	Do not believe in what you have fancied, thinking that, because it is extraordinary, it must have been inspired by a god or other wonderful being.
–	Do not believe anything merely because presumption is in its favor, or because the custom of many years inclines you to take it as true.
–	Do not believe anything merely on the authority of your teachers and priests.
–	But, whatever, after thorough investigation and reflection, you find to agree with reason and experience, as conducive to the good and benefit of one and all and of the world at large, accept only that as true, and shape your life in accordance with it.

The same text, said the Buddha, must be applied to his own teachings.

As they sat there, the Kalamas of Kesaputta said to the Blessed One, "Lord, there are some brahmans & contemplatives who come to Kesaputta. They expound & glorify their own doctrines, but as for the doctrines of others, they deprecate them, revile them, show contempt for them, & disparage them. And then other brahmans & contemplatives come to Kesaputta. They expound & glorify their own doctrines, but as for the doctrines of others, they deprecate them, revile them, show contempt for them, & disparage them. They leave us absolutely uncertain & in doubt: Which of these venerable brahmans & contemplatives are speaking the truth, and which ones are lying?"

"Of course you are uncertain, Kalamas. Of course you are in doubt. When there are reasons for doubt, uncertainty is born. So in this case, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering' — then you should abandon them.

"What do you think, Kalamas? When greed arises in a person, does it arise for welfare or for harm?"

"For harm, lord."

"And this greedy person, overcome by greed, his mind possessed by greed, kills living beings, takes what is not given, goes after another person's wife, tells lies, and induces others to do likewise, all of which is for long-term harm & suffering."

"Yes, lord."

"Now, what do you think, Kalamas? When aversion arises in a person, does it arise for welfare or for harm?"

"For harm, lord."

"And this aversive person, overcome by aversion, his mind possessed by aversion, kills living beings, takes what is not given, goes after another person's wife, tells lies, and induces others to do likewise, all of which is for long-term harm & suffering."

"Yes, lord."

"Now, what do you think, Kalamas? When delusion arises in a person, does it arise for welfare or for harm?"

"For harm, lord."

"And this deluded person, overcome by delusion, his mind possessed by delusion, kills living beings, takes what is not given, goes after another person's wife, tells lies, and induces others to do likewise, all of which is for long-term harm & suffering."

"Yes, lord."

"So what do you think, Kalamas: Are these qualities skillful or unskillful?"

"Unskillful, lord."

"Blameworthy or blameless?"

"Blameworthy, lord."

"Criticized by the wise or praised by the wise?"

"Criticized by the wise, lord."

"When adopted & carried out, do they lead to harm & to suffering, or not?"

"When adopted & carried out, they lead to harm & to suffering. That is how it appears to us."

"So, as I said, Kalamas: 'Don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, "This contemplative is our teacher." When you know for yourselves that, "These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering" — then you should abandon them.' Thus was it said. And in reference to this was it said.

"Now, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are skillful; these qualities are blameless; these qualities are praised by the wise; these qualities, when adopted & carried out, lead to welfare & to happiness' — then you should enter & remain in them.
