There is not one spark of real enjoyment there...

The idea that the gratification of the senses constitutes enjoyment is purely materialistic.There is not one spark of real enjoyment there; all the joy you find in it is a mere reflection of the true bliss.

Swami Vivekananda at a retreat given at the Thousand Island Park, USA. June 25, 1895. Complete Works, 7.16.

The Lord looks into a man's heart...

The Lord looks into a man's heart and does not judge him by what he does or where he lives.   
p. 204 The Gospel of Sri Ramakrishna

  

Seek the science of the maker and not that of the made.

Do all as a sacrifice or offering to the Lord. Be in the world, but not of it, like the lotus leaf whose roots are in the mud but which remains always pure. Let your love go to all, whatever they do to you. .... Do not want this world, because what you desire you get. Seek the Lord and the Lord only. The more power there is, the more bondage, the more fear. How much more afraid and miserable are we than the ant! Get out of it all and come to the Lord. Seek the science of the maker and not that of the made.

Swami Vivekananda in a Letter to Swami Brahmananda. Written in Bengali from Benares on February 18, 1902. Complete Works, 5.177.

From "The East and the West," originally written in Bengali. Complete Works, 5.534.

It is much easier to refrain from error - in speech or in activity - than to seek forgiveness for the word quickly spoken.
