Patanjali Yoga Sutras – Knowledge Sheet 12
As you all know, there are three gunas or qualities. They are sattva, rajas and tamas. Three gunas come into our life in cycles. When sattva comes, there is alertness, knowledge, interest and joy in everything. When rajo guna comes, more desires, selfishness, restlessness and sadness arise in us. When tamo guna comes, delusion, attachment, lack of knowledge, lethargy, all this comes. These three come in life, turn by turn.
Everyone loves in this world. Everything loves, but that love does not stay too long as love. It immediately becomes hatred, almost immediately. But yoga is that skill, that preservative which maintains love as love throughout.
