Sati at once thought of the lotus feet of her husband, Lord Siva, who is one of the three great personalities of Godhead in charge of the management of the material world, and simply by meditating on his lotus feet she derived such great pleasure that she forgot everything in relationship with her body. This pleasure was certainly material because she gave up her body for another body that was also material, but by this example we can appreciate the devotees pleasure in concentrating his mind and attention on the lotus feet of the Supreme Lord, Visnu, or Krsna. There is such transcendental bliss in simply meditating on the lotus feet of the Lord that one can forget everything but the Lords transcendental form. This is the perfection of yogic samadhi, or ecstasy. In this verse it is stated that by such meditation she became free from all contamination. What was that contamination? The contamination was her concept of the body derived from Daksa, but she forgot that bodily relationship in trance. The purport is that when one becomes free from all bodily relationships within this material world and simply places himself in the position of an eternal servant of the Supreme Lord, it is to be understood that all the contamination of his material attachment has been burned by the blazing fires of transcendental ecstasy. It is not necessary for one to manifest a blazing fire externally, for if one forgets all his bodily relationships within this material world and becomes situated in his spiritual identity, it is said that one has been freed from all material contamination by the blazing fire of yogic samadhi, or ecstasy. That is the topmost perfection of yoga. If one keeps his bodily relationships within this material world and poses himself as a great yogi, he is not a bona fide yogi. In Srimad-Bhagavatam (2.4.15) it is stated, yat-kirtanam yat-smaranam. Simply by chanting the holy name of the Supreme Personality of Godhead, simply by remembering the lotus feet of Krsna, simply by offering prayers to the Supreme Personality of Godhead, one is immediately freed from material contamination, the material bodily concept, by the blazing fire of ecstasy. This effect takes place immediately, without a seconds delay.
