מ"מ יזכה לדביקות מחמת התבודדות מבני אדם ומחמת שכותב רזי תורה ומחמת יחודים כידוע מהאר"י ז"ל וכשיעשה יחודים יחשוב באותה שעה בגדולתו יתברך כפי כחו.
How does a person merit adhesion (Dveikut) to HaShem, blessed is He? By secluding (Hitbodedut) yourself from others, by writing the secrets of the Torah, and through unifications (Yichudim) to HaShem, as known from the teachings of the Godly Rabbi Yitzchak Luria (the Arizal), of blessed memory. When involved in unifications (Yichudim), contemplate the greatness of HaShem, blessed is He, to the full extent of your ability.¹³¹
