The mystic who worships the Supersoul within himself is also an ātmārāma. The ātmārāma yogīs are of two kinds: sagarbha and nigarbha. It is stated in Śrīmad-Bhāgavatam (SB 2.2.8): "Some yogīs meditate within their heart on the localized Viṣṇu, who is four-handed and who holds four symbols: conch, disc, mace and lotus." The yogī who thinks of the four-handed Viṣṇu becomes absorbed in devotional ecstasy and shows the symptoms of that state. Sometimes he cries, and sometimes he feels separation from the Lord. In this way he merges in transcendental bliss, resulting in his becoming entrapped like a fish.
The sagarbha and nigarbha yogīs can be further divided into three categories: the beginner, the advanced yogī, and he who has attained perfection. These yogīs are described in the Sixth Chapter of the Bhagavad-gītā. Those who are trying to ascend the path of mystic yoga are called ārurukṣu-yogīs, beginners. In ārurukṣu yoga, one practices various sitting postures and concentrates the mind. One ascends the path of yoga by means of meditation and detachment, and when one is no longer attached to working for sense gratification, he gradually becomes free. At that time he attains a state of ecstasy called yogārūḍha. If such a mystic yogī somehow or other comes in contact with a saintly person, he becomes a devotee of Kṛṣṇa.
