I have to disagree with Originalji's interpretation, but then I would, would I not.
I think the concept is personal, but I wish share what it means to me, it is not so much a state of pleasure, more a state where you cannot be hurt, damaged, pained. I feel this is not a state that one can switch on or off, or meditate to reach, but first one has to plant the seeds of Chardi Kala, to me, this means doing everything that will bring as little future problems as possible, so in effect, to live by way of a code of truth, not just simply telling the truth, but being true. This requires wisdom and learning, experience, perception, discipline. The discipline gets easier as the truth becomes habit and ultimately becomes the self.,
I dislike posts myself where airy fairy terms as used that sound great but impart little to the reader, so my definition of living by the truth is to present yourself to the world in the best possible light you can, to act as best you can, to avoid anything that will come back and bite you, on a most basic level, eat well, keep in good shape, avoid anything that changes you the way you think, including drink, drugs, porn, fantasy, anything that changes the shape of your brain, that makes such actions acceptable and justifiable, be not a slave to love, be a master of love, be a love giver, not a love taker, reject the notion of needing love, accept people as they are, do not foist any need to be loved on relationships, tell the truth unless such action is against the notion of the truth, (1984, are there any sikhs in your boot of your car sir?) , nothing is set in stone, run with it, pick up the ball and run with it, to the absolute best of your ability, and being aware of consequence and action, pay all your bills, don't get parking tickets, don't borrow money, value your word, don't be greedy or proud, or egoistical, do not get attached to material possessions, or even people, you are here to serve, not take, let go of envy, be happy for people, genuinely, work hard and honestly, be a good cog in this universe, not a bad one, eat and live modestly, share your love with those you trust, help everyone else to the best of your abilities given the situation, never ever put another before yourself, you need to be here to help as many as possible, you cannot blow the bank on a single situation, be in complete love with yourself, and the god within you.
From a pragmatic view, such a lifestyle brings peace, contentment and acceptance, it is not a state of utter happiness and optimism, it is a state of peace, harmony and understanding.
The grit to enable you to live in this fashion is enshrined in the 11th master.
of course the question then begs why is everyone not living in chardi kala, I would use two words 'short term'
Short term is valued above everything else, short term food, short term love, short term sex, short term pleasures, we want gratification, and we want it now, peace is boring, love making with your wife is boring, no we want women dressed as nuns, in shiny boots and filthy mouths, we don't want daal, we want chicken in the most tasty sauces with the softest of bread, washed down with a nice cold beer, and don't want it to stop, until full of our own filth we sleep, and then wake, and then have to deal with the angina, the blocked arteries, the useless liver, the various STD's, the shame, the guilt, which lasts for a few hours before the howling comes calling again, the singing, like harpies, the singing, it does not impart peace, or contentment, it is a calling, for immediate gratification, tomorrow can wait, tomorrow we look for peace, today, today there will be no peace, just the rush of blood through your veins, as you throw your head back, nose to the air, and howl with every cell in your body, at that moment, peace, balance, family, love, shame, guilt, ego, pride, nothing matters, not even death, the connection with the dark side, to go and play with the five thieves, to all go out and get drunk and have fun together, to overdose on all five, followed again by the comedown, the problems, physical, mental, financial, welcome to hell, the hell of short term, we can see what happens on the other side, but we never listen, never note, we behave like unintelligent savages, beneath a thin veneer of humanity and then pay lip service to the very concepts that will free us.
