An acceptable salah, and Khushoo
Its hard. Very hard to maintain concentration throughout. I find focusing on the translation verse by verse helps, and i can only do that by reciting arabic very slow, silent, rhythmic way.. Which helps build khushoo ( also relaxing).. And if i find my mind wandering away, i stop reading until i can regain my focus. Works most of the time.
Focusing whilst performing wudhu and and praying at earliest time also helps with concentration during salah.
The other thing is imagining things def helps, weather its sirat, grave angels, standing before god, etc.. Fear is def. needed, even if it is to just get you back on track/ in the right mood. Its the beginning point, that you work upwards from spiritually. So if it works for you, use it every time.
For me it also helps to imagine the size of the universe and our significance in comparison.., which if you think about it is very minute.. Perhaps in a funny way akin to a community of ants underground going about their daily business. ..each with their own imp roles to carry out...But not much significance in the larger scheme of things, certainly not much noticeable to us humans. If you accidentally stamped on them, you could take out a decent amount of their community in one go, but would you notice much? a little perhaps but nothing to create a fuss over i doubt.
Our significance is similar in the larger scheme of things.. But we like to make out we are the the most important beings/ creations ever, and our egos keep growing and growing. If i were God, id waver between splitting my sides and wiping out the lot. But thankfully i'm not, because God is merciful and forgiving for a reason.
Jokes aside, it does help to realise your insignificance in this world..perhaps realise the true meaning of 'allah hu akber'.. That God is the greatest... Means exactly that. Can you fathom what that means? Can a brain fathom what that entails?
That theres nothing bigger, stronger, more powerful, watchful, Knowing, loving than God, He was there from....always, And will be there forever..He is bigger than the universe and all that it entails, and if He decided to end it all tomorrow, then so it will be, there will be no naam or nishaan of us. Just imagining these things can really put things into perspective how free and independent of Him you really are. Submission then seems like the only option.
Apologies for the long post.. Didnt mean for it to go on.
