Unfortunately, man today is unable to give up addiction to even the most trivial things. Many are unable to give up cigarettes or bidis, tea or coffee. If one cannot give up such acquired tastes, how is he going to give up qualities like raga and dvesha (attachment and hatred)? (SSS Vol.25, p. 143)

When excessive desires are entertained, the will power declines. By reducing just one of your several habits like smoking or coffee addiction, you can experience an increase in your will power and intellectual ability.

When the will power is weak, even when one sits in meditation he cannot steady his mind and it will only be a waste of time. (SSS Vol.26, p. 64)
