यं यं वापि स्मरन्भावं त्यजत्यन्ते कलेवरम्।
तं तमेवैति कौन्तेय सदा तद्भावभावितः।।8.6।।
।।8.6।। हे कौन्तेय (यह जीव) अन्तकाल में जिस किसी भी भाव को स्मरण करता हुआ शरीर को त्यागता है वह सदैव उस भाव के चिन्तन के फलस्वरूप उसी भाव को ही प्राप्त होता है।।
Whatever image prominently floats in ones thoughts at the moment of death and one leaves ones physical body with that final thought one will become in their very next life. This is what Lord Krishna is stating in this verse. Their final thought will become form. Ones final thought will naturally be what was constantly reflected upon and mediated on during their span of life based upon ones association and daily habits.
