Many people say the secret, but in my opinion the secret is flawed completely plus it gives you bad intentions, it tells you to give in charity with the intention that you will recieve something back.
This is a bad intention although it might work because God blesses those who give to others and there is much proof of this in different scriptures from all religions:
He who supplies seed to the sower and bread for food will supply and multiply your resources and increase the harvest of your righteousness. You will be enriched in every way for great generosity.
Christianity. 2 Corinthians 9.6-11
1."The likeness of those who spend their wealth in Allah's way is as the likeness of a grain which grows seven ears, in every ear a hundred grains. Allah gives increase manifold to whom He will. And Allah is All-Sufficient for His creatures' needs, All-Knower." [Soorah al-Baqarah, 261] The Quran
And if you look there to find what it says about giving to recive in different scriptures and books:
He who gives his wealth to purify himself,
and confers no favor on any man for recompense,
only seeking the Face of his Lord the Most High;
He shall surely be satisfied.
Islam. Qur'an 92.18-21
Give not with the thought to gain,
and be patient unto thy Lord.
Islam. Qur'an 74.6-7
Giving simply because it is right to give, without thought of return, at a proper time, in proper circumstances, and to a worthy person, is enlightened giving. Giving with regrets or in the expectation of receiving some favor or of getting something in return, is selfish giving
.
Hinduism. Bhagavad Gita 17.20-21
It is more blessed to give than to receive.
Christianity. Acts 20.35
It also tells you to say thank you the universe repetively. The universe is creation of God not Got himself. Say thank you to God for everything you recieve and your life in abundance but say it with sincerity.
Sorry for rambling on, althought the secret has some good concepts which are found in every religion and taught such as: giving thanks, giving in charity and positive thinking. Its not a SECRET its always been known. But i got to take my hat off to her for making so many people thing its a secret. You can gain alot more than what the book tells you by having good intentions for the good than you do, trust me
Any way, inspiritational books:
The Quran
The Bible
The Torah
