The theory of chance

The theory of chance can best be explained in the Vedic literature by the
words ajnata-sukrti, which refer to pious activities performed without the
actor’s knowledge. But these are also planned. For example, Krsna comes like
an ordinary human being, He comes as a devotee like Lord Caitanya, or He
sends His representative, the spiritual master, or pure devotee. This is
also the planned activity of the Supreme Personality of Godhead. They come
to canvass and educate, and thus a person in the illusory energy of the
Supreme Lord gets a chance to mix with them, talk with them and take lessons
from them, and somehow or other if a conditioned soul surrenders to such
personalities and by intimate association with them chances to become Krsna
conscious, he is saved from the material conditions of life. Krsna therefore
instructs:
sarva-dharman parityajya
mam ekam saranam vraja
aham tvam sarva-papebhyo
moksayisyami ma sucah
“Abandon all varieties of religion and just surrender unto Me. I shall
deliver you from all sinful reaction. Do not fear.” (Bg. 18.66) The word
sarva-papebhyah means “from all sinful activities.” A person who surrenders
unto Him by utilizing the chance to associate with the pure devotee,
spiritual master or other authorized incarnations of Godhead, like Prthu
Maharaja, is saved by Krsna. Then his life becomes successful.
