The actions and reactions of the three modes of material nature are visible in this life. For example, some people are very happy, some are very distressed, and some are in mixed happiness and distress. This is the result of past association with the modes of material nature — goodness, passion and ignorance. Since these varieties are visible in this life, we may assume that the living entities, according to their association with the different modes of material nature, will be happy, distressed or between the two in their next lives also. Therefore the best policy is to disassociate oneself from the three modes of material nature and be always transcendental to their contamination. This is possible only when one fully engages in the devotional service of the Lord. As Kṛṣṇa confirms in Bhagavad-gītā (14.26):
māṁ ca yo ’vyabhicāreṇa
sa guṇān samatītyaitān
“One who engages in full devotional service, who does not fall down under any circumstance, at once transcends the modes of material nature and thus comes to the spiritual platform.” Unless one is fully absorbed in the service of the Lord, one is subject to the contamination of the three modes of material nature and must therefore suffer from distress or mixed happiness and distress.
