Yamuna : In San Francisco, the morning walks were one of the most relishable, glorious times with him. I generally wanted to be on the morning walk. One of the other devotees and I used to get up at two in the morning, pick flowers in Golden Gate Park, make garlands for Srila Prabhupada, present them to him, and go on the morning walk.
Those moments in the park were always very special for us, walking next to our spiritual master and trying to chant Hare Krishna just as he chanted Hare Krishna. He walked like a young man of twenty-five. The first day I went, I was wearing wooden yogi shoes, and my feet bled because Srila Prabhupada was walking so fast.
