“Friendship is one mind in two bodies.”

“To be capable of steady friendship or lasting love, are the two greatest proofs, not only of goodness of heart, but of strength of mind.”

“Friendship: A ship big enough for two in fair weather, but only one in foul.”

“True enjoyment comes from activity of the mind and exercise of the body; the two are ever united.”

“I had three chairs in my house; one for solitude, two for friendship, three for society.”

“Friendship is almost always the union of a part of one mind with the part of another; people are friends in spots.”

“Two people who are true friends are like two bodies with one soul”

“If the body dies, it does no harm to the mind, but if the mind dies, one can no longer act as a man even though the body survives.”

“That which rises in this body as 'I' is the mind. If one enquires 'In which place in the body does the thought 'I' rise first?', it will be known to be in the heart [spiritual heart is 'two digits to the right from the centre of the chest']. Even if one incessantly thinks 'I', 'I', it will lead to that place (Self)'.”

“Of escape there are but three methods — two chimerical and a third real. The first two are the dram-shop and the church, debauchery of the body or debauchery of the mind; the third is social revolution.”
