As a bundle of eight metals loaded in a boat will reach the other bank without any change in its form or colour during transit,
When these metals are put in fire, they melt and acquire the form of fire. It is then turned into beautiful ornaments of metal better looking than each individually.
But when it comes in contact with philosopher-stone, it turns into gold. Beside becoming invaluable, it also becomes beautiful and attractive to look at.
Similarly in the company of God-oriented and holy men, one becomes holy. Meeting with True Guru, the Supreme of all philosopher-stones, one becomes like a philosopher-stone. (166)
