Just as springtime in the present indicates the nature of springtimes in the past and future, so this life of happiness, distress or a mixture of both gives evidence concerning the religious and irreligious activities of one’s past and future lives.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
वर्तमानोऽन्ययोः कालो गुणाभिज्ञापको यथा । एवं जन्मान्ययोरेतद्धर्माधर्मनिदर्शनम्
vartamāno'nyayoḥ kālo guṇābhijñāpako yathā | evaṃ janmānyayoretaddharmādharmanidarśanam
