Sins

aparaadh sahasraani kriyanteaharnisham maya|
taani sarvani me dev kshamasva purushottam ||
Hey Purushottam , ! day and night I have been doing thousands of sins kindly forgive them all !! WHen we ask with remorse we must remember HOW LORD has saved others from hienous crimes and its sins .

Suvarnasteya :
Goddess laxmi is ever present in gold , so stealing gold is sin towards goddess . This sin was committed for the first time by bali . Bali once stole the kirit [ crown ] of lord narayana sleeping in the ksheerasagar [ amukta sthana ] . Garuda chased bali and grabbed it . But garuda placed it on the head of krishna in dwapara yuga while he was in gomantaka parvat . This crown fitted exactly the head of krishna establishing that there is no differenece between lord narayana and krishna .
Bali indirectly became the instrument for such a exhibition of quality of narayana . Bali infact got punya rather than sin for his acts , such is the magnanimity of lord towards his devotees .

Shatdahnva and kritavarma alongwith these two akrur participated in the filching of syamantak mani . Akrur hid the mani in his clothes from krishna . Lord forgave him and also allowed him to keep the ruby .

Suraapaan :
Sons of kubera , nalkubar and manigreeva , after consuming alcohol , nakedly were sporting in ganga with many women .narada cursed them to be arjuna trees . Krishna mitigated their sins and curse by his touch .
All yadavas drank mayreyak alcohol and in ensuing brawl killed themselves but their act resulted in the krishna leaving for paramdham thus giving them more punya .

Gurupatnigaman:
Moon chandra indulged with wife of his preceptor brahaspati and had to suffer kushta [ leprosy] . But lord saved him from hell by taking birth in his lineage of chandravansha as krishna . Krishna brought enormous fame to the lineage of chandra and therby as his forefather [ mane ] moon was exonerated .

Pataki sanyog :
When we befriend pataki sinner we share his sins . Ravan kumbakarna ,shishupala dantavaktra , hiranyaksha hiranyakashipu , nalkubar manigreeva all these were residing in the same body alongwith the demons , jay vijay , dhuni chamu ,
Similarly putana had both urvashi and tataki . Karna had surya and dambodhbhav lord krishna saved all these good souls even when they were in pataki sanyog ,
Kansa minister akrur or his sairandhri trivakra everyone were freed from sins by lord krishna .

Thus when mahapatakas can be forgiven by lord krishna by bringing pashchattap among the devotees and through prayashchitta , then small patakas or upapatakas wil also be destroyed by lord . He forgave
1.Shringi for giving curse to a sane king parikshit
2.Kaliya snake for biting him in yamuna
3.Ajamila bramhin for veshya gaman
4.Gandhari for cursing krishna to exterminate yadava lineage
5.King satrajit for false allegation of syamantakmani apahaar .
Thus lord forgives when devotee does prayaschitta through his samsmaranam by meditating all these events of hari and paschattap and homa japa dana etc . Krichcha is the best form of prayaschitta . All such prayaschitta should
start from dwadashi tithi.
