"the secret" and the bhagavad gita

"the secret" book mentions that "thoughts are things". What we think about, we attract to ourselves. what we think, we become. Specifically, it is suggested that we think thoughts of what we want to become or attract to ourselves before going to sleep, because the last thought before falling asleep stays in the subconscious and repeats during sleep. In the bhagavad gita, Krishna says that whatever man thinks of at the time of death, he will attain in his next life. If he thinks of Krishna, he will come straight to Krishna. The 'last thought' before sleep as well as before death is thus significant. Both books stress the power of thoughts, and the power of the subconscious to manifest reality.
