Sri Ramakrishna

There are three kinds of love.

Unselfish, mutual and selfish.

The unselfish love is of the highest kind.

the lover only minds the welfare of the beloved and does not care for their own sufferings.

In mutual love, the lover not only wants the happiness of their beloved, but has an eye towards their own happiness also.

It is middling.

The selfish love is the lowest.

It only looks towards its own happiness, no matter whether the beloved suffers weal or woe.

... ...

The supreme purpose and goal for human life is to cultivate love.

You should love everyone because God dwells in all beings.

But although God is in all people, all people are not in God.

That is why we suffer.

It is on account of the ego that one is not able to see God.

In front of the door of God's mansion lies a stump of ego.

one cannot enter the mansion without jumping over the stump.

If you wish to be great, be lowly and meek, for great people have the nature of a child.

But do not be small-minded,

Do not pray for gourds and pumpkins from God when you should be asking for pure love and pure knowledge to dawn within every heart.

One person may read holy scriptures by the light of a lamp and another may commit a forgery by that very light.
