Connection with the tzaddik (righteous holy Jew) is most pronounced in the sefer No'am Elimelech. To have a closer relationship with the tzaddik you must follow what the tzaddik advises you. The tzaddik is very attached to all Jews because he wants to be a conduit for Hashem’s blessing. The tzaddik can influence and attach himself to a sinner. The “aveira lishmah” (a sin done with pure intent) that the Tzaddik has to “perform” to attach himself to the sinner is very great.
