jive saksat nahi tate guru caittya-rupe
siksa-guru haya krsna-mahanta-svarupe
jive—by the living entity; saksat—direct experience; nahi—there is not; tate—therefore; guru—the spiritual master; caittya-rupe—in the form of the Supersoul; siksa-guru—the spiritual master who instructs; haya—appears; krsna—Krsna, the Supreme Personality of Godhead; mahanta—the topmost devotee; sva-rupe—in the form of.
Since one cannot visually experience the presence of the Supersoul, He appears before us as a liberated devotee. Such a spiritual master is none other than Krsna Himself.
It is not possible for a conditioned soul to directly meet Krsna, the Supreme Personality of Godhead, but if one becomes a sincere devotee and seriously engages in devotional service, Lord Krsna sends an instructing spiritual master to show him favor and invoke his dormant propensity for serving the Supreme. The preceptor appears before the external senses of the fortunate conditioned soul, and at the same time the devotee is guided from within by the caittya-guru, Krsna, who is seated as the spiritual master within the heart of the living entity.
