This question has been bogging mankind from eternity and will remain so forever.
We live in various strata of society with differing social, cultural and economic life. Even those who live below poverty line wonder and struggle for a pint of peace. They are drowned in the miseries of life and the rigmarole squeezes their daily living with wants surrounding them; with pains of living and diseases befriending them.
Those in plenty are not free from trouble. They are free from daily wants and needs, surrounded by servants, cars and gadgets to ease the pain of living. But the demands of higher pleasurable life leaves its own trail of pain and anxieties.
What is it that one requires to reach the goal of inner peace, solace and solitude amidst all the demands of life, turmoils, rigmaroles, pain and suffering?
Those who are enjoying the pleasures of life, being entertained by music of night life, gastronomic foods and savories are unconsciously building in mysteriously a huge bubble inside, which waits for a moment to burst out and surround the person and those depending on them in misery, disease and poverty.
If one is looking for peace amongst the plenty or in midst of turmoils then mere practice of yoga, silence and meditation is not sufficient and enough. There is something more to cling to reach the goal set by life. It is the sum total of living which mysteriously builds up the inner peace automatically. For which at every point we need to let go off the huge burden carried on our shoulders. The burden of complains, woes, pains related to the failures, hurts given by others, bad memories, filthy ideas, wrongs and suffering caused by us to others, sufferings given by us to others which has created bad karmas for us. The road to peace, solace and solitude is to lessen this daily accumulation of bad karmas or bad deeds and instead in its place to increase acts of good heavenly deeds. Deeds as simple as feeding ants with half a spoon of sugar once awhile. Throwing crumbs of food to stray dogs, to birds and stray cows. Feed them with water tankers to slums where water shortage troubles them. If you think that such acts of goodness and charity is beyond your means and purse than utilize your free time to spread goodness by choosing any of the umpteen ways of good deeds.
Goodness, compassion, humility and simplicity will certainly ease the burden of life. Smile gets smile. Show mercy, mercy will be shown to you.
Watch TV shows discreetly as evil contents like sex dances, violent scenes, scenes of quarrels, bickering, arguments will add to your inner psyche to trouble you. Sex dances and sex scenes appeases the passions and it will have negative impact. Make it a point to enlighten your inner knowledge, it will become a source of strength and adds to your will power and determination.
Your accumulation of deeds of goodness and a will to serve others to relieve their pain and suffering will add to your good karma that will fetch peace, solace, quititude. Joys from good deeds would follow so also tranquility and life will become meaningful and well lived.
