P. 91. Ruchnius (spirituality) can be in any place, it is beyond space. The tzaddik's essence can be best felt in his presence or at his kever (grave), though it is available anywhere. The sound of the giving of the Torah at Sinai has not stopped. The Torah has a greater gilui (revelation) in a beis midrash. The main thing is dveykus (attaching) with the tzaddik through thought. When the neshama is finally free from the physical world and 'goes' to Olam Haba (the World to Come), it can be fully in its natural state.
