How does one practice Buddhism when experience is limited by the 6 senses?

If one is limited by the senses and the formation of the sense, how does one practice Buddhism which espouses interrelatedness and interconnectedness? For example, if i simply taste the grape i have in mouth, how do i realize that the grape is the result of the elements of nature e.g. propagation of seed, pollination, inception of a seedling, sprout, etc which in turn is supported by the sun, rain, soil, etc
