Yoga-siddhi — The Mystic Perfections and Their Origin in Meditation on the Lord
परमाणुमये चित्तं भूतानां मयि रञ्जयन् । कालसूक्ष्मार्थतां योगी लघिमानमवाप्नुयात् ॥ १२ ॥
paramāṇu-maye cittaṁ bhūtānāṁ mayi rañjayan kāla-sūkṣmārthatāṁ yogī laghimānam avāpnuyāt
瑜伽行者若令心系于我——我遍在万物,亦为诸元素原子成分之精髓——便能体悟时间之极微细相,而得名为“laghimā(轻妙)”之成就。
Śrīmad-Bhāgavatam elaborately explains that kāla, or time, is the transcendental form of the Lord that moves the material world. Since the five gross elements are composed of atoms, the atomic particles are the subtle substance or manifestation of the movements of time. More subtle than time is the Personality of Godhead Himself, who expands His potency as the time factor. By understanding all these things clearly the yogī obtains laghimā-siddhi, or the power to make himself lighter than the lightest.
In 11.15.12, Kṛṣṇa explains that by absorbing the mind in Him as present within all beings down to the atomic level, a yogī gains extreme subtlety and attains laghimā—the power of becoming very light.
In the Uddhava-gītā (Canto 11), Kṛṣṇa instructs Uddhava on paths of devotion, knowledge, and yoga; while describing aṣṭa-siddhis, He shows how such powers arise from disciplined meditation, yet remain secondary to devotion to Him.
Practice seeing the Divine presence in all beings, cultivate deep attentiveness and humility, and use meditation to refine awareness—seeking inner purification and devotion rather than fascination with extraordinary abilities.
