The fine Samskaras are to be conquered by resolving them into their causal state.
In plain words: Samskaras are deep, hidden impressions left in the mind by past actions and thoughts. The finest of them cannot be removed by meditation alone. They fade only when the mind itself dissolves back into its source, the sense of "I" (called Asmita, or ego).
Samskaras are the subtle impressions that manifest themselves into gross forms later on. How are these fine Samskaras to be controlled? By resolving the effect into its cause. When the Chitta, which is an effect, is resolved into its cause, Asmita or Egoism, then only, the fine impressions die along with it. Meditation cannot destroy these.
Namaste.
