Zu Beginn und am Ende des Japa soll man wahrlich die Zügelung des Prāṇa (Prāṇa-saṃyama) ausüben. Und dann, beim Abschluss, soll man das glückverheißende Bīja-Mantra hundertachtmal rezitieren.
Suta Goswami (narrating Shiva-upasana procedures to the sages of Naimisharanya)
It prescribes a core Shaiva practice: bracketing japa with prāṇa-saṃyama and sealing the rite by repeating the bīja 108 times, strengthening focus (ekāgratā) and devotional potency in Linga-upāsanā.
By linking breath-discipline and seed-mantra, it implies Shiva as Pati—the inner Lord accessible through refined prāṇa and mantra-śakti—guiding the pashu (soul) beyond pasha (bondage) via disciplined upāsanā.
Prāṇa-saṃyama (a pranayama-like restraint of vital breath) performed at the start and end of japa, followed by 108 repetitions of the bīja-mantra as a concluding (saṃhāra/saṃpūraṇa) act.
