Happiness can be classified into four categories
sāttvikaṁ sukhamātmotthaṁ viṣhayotthaṁ tu rājasam
tāmasaṁ moha dainyotthaṁ nirguṇaṁ madapāśhrayām
(Bhāgavatam 11.25.29)[v21]
Tāmasic
happiness. This is the pleasure derived from narcotics, alcohol, cigarettes, meat products, violence, sleep, etc.
Rājasic
happiness. This is the pleasure from the gratification of the five senses and the mind.
Sāttvic
happiness. This is the pleasure experienced through practicing virtues, such as compassion, service to others, cultivation of knowledge, stilling of the mind, etc. It includes the bliss of self-realization experienced by the
jñānīs
when they stabilize the mind upon the soul.
Nirguṇa
happiness. This is the divine bliss of God, which is infinite in extent. Shree Krishna explains that the yogi who becomes free from material contamination and becomes united with God attains this highest state of perfect happiness. He has called this unlimited bliss in verse 5.21 and supreme bliss in verse 6.21.
