On Teshuva process

According to Rabbi Soloveitchik, teshuva:

"It is a precept whose essence is not in the performance of certain acts or deeds, but rather in a process that at times extends over a whole lifetime, a process that begins with remorse, with a sense of guilt, with man's increasing awareness that there is no purpose to his life, with a feeling of isolation, of being lost and adrift in a vacuum, of spiritual bankruptcy, of frustration and failure - and the road one travels is very long, until the goal of repetance is actually achieved. Repentance is not a function of single, decisive act, but grows and gains in size slowly and gradually, until the pertinent undergoes a complete metamorphosis, after becoming a new person, and only then, does repetance take place".
