Equanimity of mind, as mentioned above, is the sign of self-realization. Those who have actually attained to such a stage should be considered to have conquered material conditions, specifically birth and death. As long as one identifies with this body, he is considered a conditioned soul, but as soon as he is elevated to the stage of equanimity through realization of self, he is liberated from conditional life. In other words, he is no longer subject to take birth in the material world but can enter into the spiritual sky after his death. The Lord is flawless because He is without attraction or hatred. Similarly, when a living entity is without attraction or hatred, he also becomes flawless and eligible to enter into the spiritual sky. Such persons are to be considered already liberated, and their symptoms are described below.
The symptoms of the self-realized person are given herein. The first symptom is that he is not illusioned by the false identification of the body with his true self. He knows perfectly well that he is not this body, but is the fragmental portion of the Supreme Personality of Godhead. He is therefore not joyful in achieving something, nor does he lament in losing anything which is related to his body. This steadiness of mind is called sthira-buddhi, or self-intelligence. He is therefore never bewildered by mistaking the gross body for the soul, nor does he accept the body as permanent and disregard the existence of the soul. This knowledge elevates him to the station of knowing the complete science of the Absolute Truth, namely Brahman, Paramatma and Bhagavan. He thus knows his constitutional position perfectly well, without falsely trying to become one with the Supreme in all respects. This is called Brahman realization, or self-realization. Such steady consciousness is called Krsna consciousness.
Sri Yamunacarya, a great devotee in Krsna consciousness, said:
yadavadhi mama cetah krsna-padaravinde
nava-nava-rasa-dhamanudyata rantum asit
tadavadhi bata nari-sangame smaryamane
bhavati mukha-vikarah sustu nisthivanam ca
"Since I have been engaged in the transcendental loving service of Krsna, realizing ever-new pleasure in Him, whenever I think of sex pleasure, I spit at the thought, and my lips curl with distaste." A person in brahma-yoga, or Krsna consciousness, is so absorbed in the loving service of the Lord that he loses his taste for material sense pleasure altogether. The highest pleasure in terms of matter is sex pleasure. The whole world is moving under its spell, and a materialist cannot work at all without this motivation. But a person engaged in Krsna consciousness can work with greater vigor without sex pleasure, which he avoids. That is the test in spiritual realization. Spiritual realization and sex pleasure go ill together. A Krsna conscious person is not attracted to any kind of sense pleasure due to his being a liberated soul.
Material sense pleasures are due to the contact of the material senses, which are all temporary because the body itself is temporary. A liberated soul is not interested in anything which is temporary. Knowing well the joys of transcendental pleasures, how can a liberated soul agree to enjoy false pleasure? In the Padma Purana it is said:
ramante yogino 'nante satyananda-cid-atmani
iti rama-padenasau param brahmabhidhiyate
"The mystics derive unlimited transcendental pleasures from the Absolute Truth, and therefore the Supreme Absolute Truth, the Personality of Godhead, is also known as Rama."
In the Srimad-Bhagavatam also it is said:
nayam deho deha-bhajam nr-loke
kastan kaman arhate vid-bhajam ye
tapo divyam putraka yena sattvam
suddhyed yasmad brahma-saukhyam tv anantam.
"My dear sons, there is no reason to labor very hard for sense pleasure while in this human form of life; such pleasures are available to the stool-eaters [hogs]. Rather, you should undergo penances in this life by which your existence will be purified, and, as a result, you will be able to enjoy unlimited transcendental bliss." (Bhag. 5.5.1)
Therefore, those who are true yogis or learned transcendentalists are not attracted by sense pleasures, which are the causes of continuous material existence. The more one is addicted to material pleasures, the more he is entrapped by material miseries.
