A few quotes from the Rabbi on 'Customs of Israel'
in which he teaches to pray for all one's needs and lacks, for such prayers come from the heart's depths
'Hear our voices, LORD our God'. One should attend to praying for all one's needs and lacks, and for all things one wishes to do that day - pray for success, welfare and blessing, pray to find a match for oneself or for one's sons and daughters, for successful commerce or because of any hardship in one's household - for all one's needs. Such prayer comes from the heart and is not perfunctory.
One should also understand that there is nothing - present, past or future – that is not a matter of Divine providence. Do not think that anything is simply the result of nature, luck, or effort. So many have gone to great lengths and efforts, to no avail. One should entrust oneself to God and believe in Him, and not abandon Torah and prayer.
