Thinking of objects, attachment to them is formed in a man. From attachment longing, and from longing anger grows.
Swami VivekanandaAll the forces that we see in nature, such as gravitation, attraction, and repulsion, or as thought, feeling, and nervous motion - all these various forces resolve into that Prana, and the vibration of the Prana ceases. In that state it remains until the beginning of the next cycle. Prana then begins to vibrate, and that vibration acts upon the Akasha, and all these forms are thrown out in regular succession.
Swami VivekanandaOnly love for the Supreme Lord is true Bhakti. Love for any other being, however great, is not Bhakti. The "Supreme Lord" here means Ishvara, the concept of which transcends what you in the West mean by the personal God. "He from whom this universe proceeds, in whom it rests, and to whom it returns, He is Ishvara, the Eternal, the Pure, the All-Merciful, the Almighty, the Ever-Free, the All-Knowing, the Teacher of all teachers, the Lord who of His own nature is inexpressible Love."
Swami Vivekananda
