According to material vision, our beloved spiritual master, guide and friend, His Divine Grace A.C. Bhaktivedanta Swami Prabhupāda died on November 14, 1977, but in reality is still present. As Śrīla Prabhupāda often pointed out, there are two ways to associate with the spiritual master: through his physical presence (vapu) and his instructions (vāṇī). Sometimes we can associate with the spiritual master through his physical presence and others not, but we can always associate with him through his instructions. – The Science of Self-Realization Download: httpsia://903103.usarchive.org/20/items/ciencia_auto/ciencia_auto.pdf Paper: https://amzn.eu//4dp3mND
