EQ, SQ (spiritual quotient), well-being & Tamas/rajas/satva (Indian philosophy) personality has any key link?

Answer 1

Clearly the sattvic guna (truth, wisdom, godliness) is predominant in anyone who is an enthusiast for spirituality. Tamas (lethargy, sloth, indolence) is contrary both to spirituality and to emotional intelligence. Rajas (activity) can be directed to spiritual and/or emotional progress, but doesn't have to be. Rajas is also the guna that stimulates worldly activity and is equally available for helpful and harmful purposes. cf Bhishma in the Gita.
