8.167

言此後有愛，復能發起喜貪俱行愛，喜貪俱行愛者是緣現境起，俱由此愛緣未來自體愛未來身故，於現在境亦能生愛故名俱行愛，由後有愛為因，又以現在與妙境相應起愛故於未來妙境亦起彼彼喜愛，故彼彼喜愛亦由俱行愛為緣也。

Regarding the statement that this craving for subsequent existence can further generate craving conjoined with joy and greed: craving conjoined with joy and greed arises conditioned upon present objects. Because this craving takes the future self-substance as an object and craves the future body, it can also produce craving toward present objects; hence it is called 'conjoined craving.' It takes the craving for subsequent existence as its cause. Furthermore, because it gives rise to craving in conjunction with wonderful objects in the present, it also gives rise to diverse delights and cravings toward future wonderful objects; therefore, diverse delights and cravings also take conjoined craving as their condition.
