We build in thought the conditions that will later come into manifestation on the physical plane.

If you seem to yourself to be lacking in certain necessary qualities, if your character seems to lack strength, ask God to give you what you need - and He will. You can build any quality into your mentality by meditating upon that quality every day.

Read The Golden Key several times. Do exactly what it says, and if you are persistent enough you will overcome any difficulty.

We grow into that which we admire.

Let us be merciful in our mental judgments of our brothers and sisters, for, in truth, we are all one, and the more deeply they seem to err, the more urgent is the need for us to help them with the right thought, and so make it easier for them to get free.

You must pray for yourself constantly. How could it be otherwise? We worship God by believing in Him, trusting Him, and loving Him wholeheartedly - and we can attain to that only through prayer. The sole object of our being here is that we may grow like Him - and we can do that only through prayer. The more we pray for ourselves the more power will our prayers have for any other purpose whatever; so praying for ourselves is the reverse of selfishness - it is truly glorifying God.

You are not happy because you are well. You are well because you are happy. You are not depressed because trouble has come to you, but trouble has come to you because you are depressed. You can change your thoughts and feelings, and then the outer things will come to correspond, and indeed there is no other way of working.
