To connect to a website, we need its address. To call someone, we need their number. To hear a radio station, we need to tune the radio to the station’s frequency. Similarly, before we begin an action, we need to align our mind, to connect our mind, to Ishvara. We can only do so when the level of likes and dislikes, of raaga and dvesha, has been reduced to a great extent. Is there a way, a technique, by which we can quickly calm our mind down, and tone down our likes and dislikes?
 
Shri Krishna suggests that we chant Om prior to performing any sattvic action. Doing so sets up vibrations in our system. These vibrations reduce our likes and dislikes, and clear our mind of selfish thoughts. Visualizing the symbol of Om while chanting it is even better. Om has been used in this manner by those who have faith in the scriptures, who are performing acts of sacrifice, penance or charity. The more frequently we begin actions with Om, the more we will bring sattva into our actions.
 
In the Jnyaneshwari, Sant Jnyaneshwar points out that Om has an additional feature. Normally, acts of sacrifice, penance and charity bind us through attachment to their results. By adding Om, also known as the Pranava, to the start of any action helps us focus on the action and weakens attachment to the result. He says that the chanting of Om while commencing an action is as valuable as a steady light in deep darkness, and as an able-bodied companion while travelling in a jungle.

Bhagavad Gita Verse 10, Chapter 16

kaamamaashritya dushpooram dambhamaanamadaanvitaahaa |
mohaad griheetvaasadgraahaanpravartanteshuchivrataahaa || 10 ||
 
Filled with insatiable desires, with pretentiousness, pride and arrogance, holding untrue views in delusion, they work with impure resolve.
 
kaamam : desires
aashritya : filled
dushpooram : insatiable
dambhaha : pretentiousness
maanaha : pride
madaanvitaahaa : with arrogance
mohaad : in delusion
griheetvaa : holding
asadgraahaan : untrue views
pravartante : work
ashuchihi : impure
vrataahaa : resolve
 
A major aspect of the materialistic world view is greed. Shri Krishna refers to this greed using the phrase duspooram kaamam, meaning selfish desires that can never be satisfied or fulfilled. People who follow the materialistic world view believe that one who is without selfish desires is as good as dead. They do not believe that selfless action, work that benefits someone other than themselves, is worth anything.
 
This greed propels them to dambhaha or pretentiousness. They do not see the harm in putting on a show in order to gain favours or get what they want. As they accumulate more wealth and power, they feed their superiority complex, resulting in maanaha or excessive pride. When their pride reaches greater and greater heights, they become drunk with their ill-gotten accomplishments and possessions. This is mada, intoxication.
 
We keep coming back to the theme of ignorance and delusion, of moha, when we analyze the materialistic world view. When one cannot tell right from wrong, one begins to develop views that are not based on truth or rationality, termed in the shloka as moha-asat. It is no surprise that the activities or undertakings of such people are impure, lawless, without any consideration of duty or the big picture. Defrauding others or destroying others property are illegal in the eyes of the law, but perfectly legal from their standpoint.
