And "withdrawal from the world" is nothing but the destruction of passions and manifestation of the innermost life in Christ.

This purity is attained through conquering the passions.

Some important ideas from the book of early Christians which is called Philokalia: From Spiritual Directions of Diadochus of Photiki The acme of faith is... immersion of the mind in God. The acme of freedom from wealth is to desire to be possessionless even as others desire to possess. The acme of humbleness is to forget unfalteringly good deeds of oneself. The acme of love is to enhance your friendly attitude to those who insult and revile you.

Only when we rid ourselves of passions and lust and put the desires of flesh under the control of Spi­rit, only then we accept the cross and follow Christ. And "withdrawal from the world" is nothing but the destruction of passions and manifestation of the innermost life in Christ.

Love takes nothing: how can it take something? Everything belongs to it. It does not say, "This is mine! And this is mine!" But it says: "This is yours!"

... Do not let the deeds and thoughts of other people confuse you; let them not prompt you to do or say anything evil!
