Whatever the mind of man can conceive and believe, it can achieve.
To be more childlike, you don't have to give up being an adult. The fully integrated person is capable of being both an adult and a child simultaneously. Recapture the childlike feelings of wide-eyed excitement, spontaneous appreciation, cutting loose, and being full of awe and wonder at this magnificent universe.
People talk about physical fitness, but mental health is equally important. I see people suffering, and their families feel a sense of shame about it, which doesn't help. One needs support and understanding. I am now working on an initiative to create awareness about anxiety and depression and help people.
Mental prayer in my opinion is nothing else than an intimate sharing between friends; it means taking time frequently to be alone with Him who we know loves us. The important thing is not to think much but to love much and so do that which best stirs you to love. Love is not great delight but desire to please God in everything.
Those who give themselves to prayer should in a special manner have always a devotion to St. Joseph; for I know not how any man can think of the Queen of the angels, during the time that she suffered so much with the Infant Jesus, without giving thanks to St. Joseph for the services he rendered them then.
A beginner must look on himself as one setting out to make a garden for his Lord's pleasure, on most unfruitful soil which abounds in weeds. His Majesty roots up the weeds and will put in good plants instead. Let us reckon that this is already done when the soul decides to practice prayer and has begun to do so.
