Bhagavad Gita

ಕರ್ಮೇಂದ್ರಿಯಾಣಿ ಸಂಯಮ್ಯ ಯ ಆಸ್ತೇ ಮನಸಾ ಚರನ್ ।
ಇಂದ್ರಿಯಾರ್ಥಾನ್ ವಿಮೂಢಾತ್ಮಾ ಮಿಥ್ಯಾಚಾರಃ ಸ ಉಚ್ಯತೇ ॥೬॥
karmeṃdriyāṇi saṃyamya ya āste manasā caran |
iṃdriyārthān vimūḍhātmā mithyācāraḥ sa ucyate ||6||

Gist of the sloka:
One who for the outside world shows control over his sense, but mentally seeks them is a deluding himself and is a pretender.
Lord Krishna has very important message in this verse. In the present day, more elaborate the costume, decorations more impressed are the people. They equate the beauty with knowledge. They have no clue as to his real worth which is not visible to outside. We too out of fear, project the image of a piousness which we might not have.
Lord Krishna denounces this as fraud, on the scriptures and dharmas. We first deceive ourselves with these actions. We should never deceive ourselves. We should first have a clean heart and mind, leading to clean actions Without which one cannot elevate ourselves.
To mislead oneself and the world, if one demonstrates control over the senses but internally enjoys them, such a person will never elevate himself and is a deluded person.
