Action purifies his mind and makes the mind fit for the practice of steady meditation. Action leads to steady concentration and meditation.For the sage who is enthroned in Yoga? Sama or renunciation of actions is said to be the means.The more perfectly he abstains from actions? the more steady his mind is? and the more peaceful,he is? the more easily and thoroughly does his mind get fixed in the Self. For a Brahmana there is no wealth like unto the knowledge of oneness and homogeneity (of the Self in all beings)? truthfulness? good character? steadiness? harmlessness? straightforwardness and renunciation of all actions. (Mahabharata? Santi Parva? 175.38)

The process of linking oneself with the Supreme is called yoga. It may be compared to a ladder for attaining the topmost spiritual realization. This ladder begins from the lowest material condition of the living entity and rises up to perfect self-realization in pure spiritual life. According to various elevations, different parts of the ladder are known by different names. But all in all, the complete ladder is called yoga and may be divided into three parts, namely jñāna-yoga, dhyāna-yoga and bhakti-yoga. The beginning of the ladder is called the yogārurukṣu stage, and the highest rung is called yogārūḍha. Concerning the eightfold yoga system, attempts in the beginning to enter into meditation through regulative principles of life and practice of different sitting postures (which are more or less bodily exercises) are considered fruitive material activities. All such activities lead to achieving perfect mental equilibrium to control the senses. When one is accomplished in the practice of meditation, he ceases all disturbing mental activities. A Kṛṣṇa conscious person, however, is situated from the beginning on the platform of meditation because he always thinks of Kṛṣṇa. And, being constantly engaged in the service of Kṛṣṇa, he is considered to have ceased all material activities.
