If, during the woman’s fertile movement, the man’s seed is placed on the right side, a son is obtained—especially when union occurs at a time free from inauspicious planetary influences. In such regulated conception, the paśu (embodied soul) enters a body under cleaner pāśa (bondage), becoming more fit for later Śiva-sādhana directed to the Pati, Lord Mahādeva.
Suta Goswami (narrating Purāṇic injunctions to the sages of Naimisharanya)
It links dharmic timing and bodily discipline to spiritual fitness—suggesting that purity of kāla (time) and niyama supports a life more capable of Linga-centered Shiva-sadhana.
Implicitly, Shiva is the Pati beyond grahas and karmic afflictions; by reducing inauspicious conditions at conception, the pashu’s embodied life becomes less obstructed in turning toward the Pati.
Auspicious-time observance (kāla-śuddhi) using jyotiṣa considerations—avoiding pāpa-graha influence—functioning as a samskāra that supports later Shaiva vrata, japa, and Pāśupata-oriented discipline.
