Vita devoid of, free from
Raga desire, passion, love, affection Visayam an object
Or, by contemplating on enlightened sages who are free from desires and attachments, calm and tranquil, or by contemplating divine objects.
Vyasa, Suka, Sankara, Ramanuja, Madhva, Vallabha, Chaitanya, Sri Aurobindo, Ramana Maharsi and Sri Ramakrishna, are examples of men of enlightenment. If the sadhaka ponders on the serene, pure state of such divine souls and follows their practices, he earns confidence, achieves firmness and develops a desireless state of mind.
Similarly, one can also contemplate each stage of an asana or each movement of breath in order to bring the citta to a state of desirelessness. If consciousness is kept free from desire, it becomes chaste. Mere withdrawal from the world does not in itself achieve this aim.
