Bachchan, who is currently shooting Prakash Jha's next film "Satyagraha" in Bhopal, said work has a "therapeutic" effect on him.
"The sun sets again and another day of turmoil comes to an end. The work is the place that I would like to be always. It is almost like a balm across an aching forehead - therapeutic. Work dissects me from the daily and hourly burdens, that man carries, perhaps right to his grave," he posted on his blog.
"The atmosphere around a unit at work is intoxicating. There is always ofcourse the feel of being aware of all about. Not just the place of work, but also matters that concern us individually. Mostly those that remain in the realm of domesticity. It is impossible to be in a situation of enactment, when thoughts and mind are occupied else where," he added.
Bachchan is also gearing up for the release of his Hollywood debut project "The Great Gatsby", which will release on May 10.
