"Sarva dharman parithyajya mam ekam sharanam vraja .. Aham tvaa sarva paapebhyo mokshaishyami maa shucha " is again an oft quoted text from gita and its equivalent appears in BIBLE and QURAN. It means
sacrifice all your karmas and dharmas to almighty
surrender unto almighty all thy deeds
surrender all your actions and take refuge in almighty alone and you shall be liberated from all your sins
thou shall surrender to me alone and thee shall be given the best results
anyone who is fully devoted to me shall never be let down by me
