By the experience of active love. Strive to love your neighbour actively and indefatigably. In as far as you advance in love you will grow surer of the reality of God and of the immortality of your soul. If you attain to perfect self-forgetfulness in the love of your neighbour, then you will believe without doubt, and no doubt can possibly enter your soul. This has been tried. This is certain.
But love, first learned in a lady's eyes,
Lives not alone immured in the brain;
But, with the motion of all elements,
Courses as swift as thought in every power,
And gives to every power a double power,
Above their functions and their offices.
I am Tarzan of the Apes. I want you. I am yours. You are mine. We live here together always in my house. I will bring you the best of fruits, the tenderest deer, the finest meats that roam the jungle. I will hunt for you. I am the greatest of the jungle fighters. I will fight for you. I am the mightiest of the jungle fighters. You are Jane Porter, I saw it in your letter. When you see this you will know that it is for you and that Tarzan of the Apes loves you.
As love is full of unbefitting strains,
All wanton as a child, skipping and vain,
Form'd by the eye and therefore, like the eye,
Full of strange shapes, of habits and of forms,
Varying in subjects as the eye doth roll
To every varied object in his glance
If you hit a pony over the nose at the outset of your acquaintance, he may not love you but he will take a deep interest in your movements ever afterwards
