After Krishna's efforts to avert the Kurukshetra war fail, as one final attempt, he tries to win Karna over to the Pandava side, but in doing so, does Krishna suggest that Draupadi would accept Karna as her sixth husband?
15 rājanyā rājakanyāś cāpy ānayantv abhiṣecanam
ṣaṣṭhe ca tvāṃ tathā kāle draupady upagamiṣyati
Let queens and princesses bring golden and silver and earthen jars (full of water) and delicious herbs and all kinds of seeds and gems, and creepers, for thy installation. During the sixth period, Draupadi also will come to thee (as a wife).
An alternate translation from here is:
हिरण्मयांश्च ते कुम्भान् राजतान् पार्थिवांस्तथा।
ओषध्यः सर्वबीजानि सर्वरत्नानि वीरुधः।।१४।।
षष्ठे त्वां च तथा काले द्रौपद्युपगमिष्यति।
Golden water pots as also silver and earthen ones (filled with water) and medicinal herbs and all sorts of seeds and gems, let the wives of kings and daughters of kings bring for your anointment (in the kingship). During the sixth period Draupadi too will come to you as to a husband.
What does "sixth period" in the above mean? And in what sense did Krishna say "will come to you" in the second line or verse?
