There will never be a "perfect" time to quit smoking. A time when you don't have any distractions or stress... If you had started today one year ago, this would not even be an issue for you today! Don't waste another year!
The concept of "mental health" in our society is defined largely by the extent to which an individual behaves in accord with the needs of the system and does so without showing signs of stress.
Non-comprehenders are often distressed. Not you, though-because with good humor you're blessed. After all, your thoughts went like this, I dare say: It was none but the Lord who made us that way.
Even if the being is not entirely purified, varieties of inspirations and powers may come down from above but this may lead to serious errors. Inspirations from above mixing with the impurities from below get all muddled up and the sadhak takes this for an absolute command. Many a sadhak has thus fallen into danger. Therefore, one must particularly lay stress on the purification of the being.
