Having spent most of my life in a dionysian pursuit, whilst at the same time trying to do good deeds, this question has vexed me for years. I joined this forum as an atheist, and soon after ended up back as a sikh again.
I abandoned the pursuit of pleasures for the simple reason that the more pleasures you chase, the more empty and worthless you feel, until, you get to the point where you cannot even look in the mirror anymore, the pleasure chasing takes over your life, you cease to measure it in any other value other than how much pleasure you have had or are having.
At the end of the day, the fun and enjoyment you get out of being a manmukh, a slave to pleasure, gets less with each day, until you end up on your knees begging for peace and contentment and you realise the value of all the simple things in life, and you ask, you shout, why didnt anyone warn me of this. But they don't warn you, they expect you to follow blindly a variety of traditions and rituals that actually have nothing to do with sikhi,
What the Sri Guru Granth Sahib Ji is saying is that to have a normal life, you can be a manmukh and there is nothing wrong with that at all. But, to have a super life, to know oneself, to know everything you want to know, to be in bliss, to be so high on life, it is like you are levitating, you need to be a gurmukh, the choice is ours, the difference is, we are aware of the choice, some are not..
