The only way to remain in transcendental knowledge is through devotional service. If we stop doing devotional service, we turn down the momentum of our spiritual practices, our devotional service. Then we can also lose some transcendental wisdom or knowledge, and then become bewildered by material situations. If we keep strong in devotional service, then our transcendental knowledge also remains strong by the mercy of Guru and Kṛṣṇa.
